Github-archive

- Expand paths for user-supplied `--location` strings. This now allows for spaces in paths and proper expansion of home directories (eg: `~`)

- Fixes PyGithub pinned version to ensure `Auth` is available

- Allows the tool to be run without passing any authentication flags (previously, to use unauthenticated, you'd have to at least pass the `--https` flag)
- Removes constraint that required `--token` and `--https` to be mutually exclusive (you can now authenticate with other tools such as Git Credential Manager instead of only SSH)
- Adds `--version` CLI flag

- Drops support for Python 3.7
- Updates dependencies

- Fixes a syntax error that led to not being able to remove the authenticated user from the user's list so their git assets weren't included twice (fixes 55)

- Overhauls subprocess error handling so output is no longer clobbered
- No longer inserts newlines (which were often formatted incorrectly) when a log entry was for a new section or action
