[BUGFIX] Use proper extractor key for download archive (840)

For less popular sites, ytdl-sub's custom download archive was not working. This was because we weren't using the right extraction key (though it still worked for YouTube, Bandcamp, Soundcloud, and others). This bugfix should now exactly match yt-dlp's and never be a problem again.

Huge thanks to Svagtlys for root-causing this 🤝

[BUGFIX] file_convert output file deleted (822)

file_convert.py:modify_entry() deletes the converted output file if the output and input file names are identical. Reordered the file deletion to avoid.

Thanks OmarAhmadyar !

[FEATURE] Add `output_options.keep_max_files` to limit number of downloads per subscription (820)

Adds a new mechanism to limit subscriptions' number of videos to an explicit number (only supported date ranges prior to this).

Example usage:

output_options:
keep_max_files: 10

will only keep 10 videos at max.

In addition:
- `keep_max_files` is bundled into the `Only Recent` preset and can be used via setting the `only_recent_max_files` override variable (see examples or README for usage).
- Changed the `date_range` variable name to `only_recent_date_range` for more clarity. Usage of `date_range` will continue to work.

[BUGFIX] Include music prebuilt presets (and all future ones) in executables (814)

ytdl-sub executables did not include the prebuilt music presets. This change fixes that and prevents the issue from happening again for any future prebuilt preset
