Vodbot

* YouTube credentials can now be downloaded from a remote source to allow any user to upload videos with VodBot.
* Added pull configuration field `client_url`, a URL to the credentials. URL must be pointing to a file accessible with HTTP/S, and be a base64 encoded JSON provided by a Google Developer Account. Default URL points to such a file provided by Friend Team Inc.
* As of the release of this update, VodBot is still not a Google-approved app, causing a popup during the authentication process about how VodBot is not trusted by Google. I can talk all I'd like about how VodBot is trustworthy, but user discretion is advised.
* Allow videos of all types beyond just archived streams to be downloaded as VODs.
* This will be separated out into different types in a later update, but for now videos such as highlights, uploads, and premieres are treated as VODs.
* Allow videos to be uploaded and notify subscribers of the channel uploaded to of the new uploaded content.
* Fixed an issue not allowing blank text (empty string) to be added to thumbnails.
* Fixed an issue with chat log display duration moving chat messages backward in time.
* Fixed an issue with chat logs not appearing if they were too close (relative to display duration) to the end of the video.
* Fixed an issue with video exports crashing VodBot when videos were not present.
* Fixed a crash with downloading videos due to an old variable.
* Fixed a crash when declaring streamers in stage arguments.
* Fixed a rare crash when attempting to locate videos not in the cache.

* Fixed an issue with exporting individual staged data.
* Note: this was also stupid.

* Fixed an issue with clip downloading crashing VodBot due to missing function arguments.
* Note: this was stupid.

* Fixed an issue with thumbnail video ID selection crashing.
* Fixed an issue with thumbnail video ID selection not exiting when it should with certain values.
* Added a shortcut to skip thumbnail video ID selection if all video IDs match the first one.
* Fixed head order and position in thumbnails not being properly accounted for.
* Optimized the processing of heads in thumbnails.
* Added a warning for out-of-bounds head orders.
* Fixed an issue where upload sizes would not display if upload chunk_size was set larger than the uploaded file's size, and removed some unnecessary extra variables for the process.
* Removed some outdated/unnecessary print statements.
* Added fields `max_workers`, `chunk_size`, `connection_retries`, and `connection_timeout` to the pull configuration section, for dictating how the worker threads pull VOD segments.

* Fixed an issue with the `vodbot init` command failing.
* Added `oauth_port` field to the upload configuration section, for dictating what port the local OAuth server should use when logging into Google services.

Major Additions/Changes:
* VodBot has changed licenses from zlib to MIT, in order to preserve crediting of work.
* VodBot now requires Python 3.7 or later, changed from requiring 3.6.
* New Python packages that have been added since last release: `argcomplete`, `dataclasses-json`, `pillow`.
* Config files have been completely reworked for internal use and better organization. The new default path to the config file is `~/.vodbot/config.json`. (40)
* VodBot will now autocomplete arguments assuming the autocompletion setup is complete. (24)
* Requires `eval "$(register-python-argcomplete vodbot)"` to be placed in your `~/.bashrc`.
* Only fully compatible with Bash, with limited compatibility with other shells. See the [argcomplete page](https://pypi.org/project/argcomplete/) for more info.
* VodBot will now cache locally pulled videos and current stages to help with auto-complete. This cache is stored in the temp directory. If, for whatever reason, the cache gets desynced with what actually exists on the disk, it can be refreshed with the `-u` argument. (55)
* VodBot can now generate, export, and upload thumbnails for videos. Details are entered during the staging process and can be enabled and configured with the config. See the wiki for details. (42)
* VodBot can now push webhooks to Discord upon completion of certain tasks. See the wiki for details. (35)

Minor changes/fixes:
* VodBot will no longer continue to prompt for things that can be provided by arguments (such as streamers when staging), and exit when an argument does not match specific criteria.
* Vods, Clips, and Chat logs can now all be saved independently and per channel as defined in the config. Master toggles for each file can be set in the pull section of the config, disabling that download for every channel.
* Chat member names, when uncolored (white), can be made into a random color if enabled in the chat section of the config. (40)
* Certain aspects of the YouTube Timed Text chat log export can be configured, such as position, anchoring, and alignment. (40)
* Stage files can now be optionally left undeleted after export or upload, configurable in the stage section of the config. (40)
* The amount of info displayed by FFmpeg (loglevel) can now be configured in the export section. Defaults to "warning". (40)
* Logs from FFmpeg are now piped to `/dev/null` by default, but can be piped elsewhere with a configuration setting.
* Export can now selectively export chat logs, videos, and/or thumbnails (when available) with each using its own toggle in the export section of the config. All toggles default to on. (40)
* Upload can now selectively upload chat logs and/or thumbnails (when available) with each using its own toggle in the upload section of the config. All toggles default to on. (40)
* Thumbnail generation has been added, along with its own section in the config as well as a new directory to be configured in the directories section. (42)
* Stream chapters (moments when the stream changes games) are now saved and displayed where relevant. (34)
* Users banned from Twitch that show up in chat logs will receive a fake username when detected. (44)
* Videos would fail to concatenate when segments of the video were muted, this has been *potentially* fixed. (51)
* Note that this still does not bypass the mute itself, simply that the video will remain intact.
* Entity codes (specifically `<`, `>`, and `&`) for YouTube Timed Text have been fixed. (48)
* Crashes related to permissions when creating directories has been fixed. (50)
* Chat parsing no longer fails when chat log is empty. (45)
* Video descriptions will no longer accept certain characters (`<` and `>`) due to issues when uploading to YouTube. (46)
* Google OAuth session information is now saved as a JSON rather than pickled. (49)
* VodBot will no longer crash when moving files across drives on Windows. (52)
* Due to Google disabling of Out-Of-Band authentication with OAuth, VodBot now uses a local server method (via localhost:8080). (60)
* Up to 1000 channels can be selected quickly by index rather than requiring full input when selecting channels for staging. (41)
* Color output is disabled when stdout is routed to a non-tty output.
