- after androidx#2738 common alac files had bit depth populated correctly, but I recently learnt that there is also 20-bit alac files (you can create them with afconvert). it doesn't make any sense and it's very complex to handle 20-bit PCM in the media3 pipelines because one byte may belong to multiple samples, but we also don't need to. create an encoding used to flag that this file is 20-bit PCM in the ALAC Format object, but expect decoders to output 24-bit or 16-bit PCM instead (playback will otherwise fail). (test file created from other test files in this repo included.)
