StreamFX v1.0.0 Beta 433 (Patreon)

Seems like I was a bit hasty on the previous release, as another regression snuck in. Had to replace most of the way FFmpeg was detected during building so it works again with the newer versions that are being shipped with OBS Studio 30.0.2. This new fix might even allow it to be used on MacOS again with less issues than before. Downside is that Linux/Ubuntu is now pinned to the system-wide FFmpeg install. Can't fix everything :(

Changelog (1.0.0b417 to 1.0.0b433)

• Fixed Regression: Detection/Linking of FFmpeg libraries for FFmpeg encoders and functionality was not working correctly.
• The PACKAGE target on Linux/Ubuntu now correctly accepts non-special characters and whitespaces.
