10cf2f455d Complete rewrite with pyloudnorm
Based on
    https://ffmpeg.org/pipermail/ffmpeg-user/2024-March/057775.html
    loudnorm is a low quality filter.
    Some research gave some alternatives.
    One of these is "pyloudnorm", a native python module implementing
    EBU R 128 loudness normalization.
    This is what I have implemented now instead of the old ffmpeg
    filter.

    In the future additional rewrites to use the official FLAC and OPUS
    encoders might be desirable for better compression.

78ee74ed9d Huge rework of this script
- Implement different conversions for lossless and lossy sources
    - Remove unused functions
    - Cleanup comments

    I noticed that FLAC --> FLAC normalisation will change the bit depth
    from 16 to 24. Wasn't able to find a simple solution for it, so I
    asked on the ffmpeg-user mailing list
