0.4.1: Fix audio in 0.4.0

Fix audio due to misconfigured libswresample (different FFmpeg version!).

0.4.0: OBS 28 Support

Emergency upd: AUDIO NOT WORKING in 0.4.0, use 0.4.1 instead

1. OBS 28 support, drop support prior to v28
2. Update Streamlink to 5.1.1
3. Use a minimized bundled FFmpeg (unnecessary components removed).
4. Use a new way to load FFmpeg binaries and Python, preventing polluting DLL search path and OBS's bin path.
5. Improve English text.
6. Fix crash when quitting OBS due to GIL.

Known issues: If other Python scripts are loaded using a user-provided Python 3.8 runtime, the user-provided runtime will conflict with the bundled one.
