feat: CrossPlatform version

- As little changes as possible, to allow future merges of upstream changes
- Even the same namespace to be a drop-in replacement
- Still comes with libmp3lame.dll for Windows, needs libmp3lame.so installed via package manager on Linux
- .NET 8.0
- Drops support for .NET Framework
- Removes FodyWeavers
- Uses NLayer in Unit tests to read MP3 files cross platform
- Uses WAV file with actual PCM content to avoid AudioFileReader trying to use Msacm32.dll which is not available on Linux
- Docker container to run tests on Linux
- NAudio 2.2.1
