penthy: evaluate flac compression quality

Are your flac files truly lossless? It is not uncommon for flac music from web sources to be upsampled or transcoded from
lossy formats. This tool harnesses the power of AI to classify an audio file as either truly lossless or transcoded from an mp3.

Even if penthy verifies a file as truly lossless in terms of mp3 transcoding, it could still be upsampled or altered in other ways.
