Allow import and playback of AAC / m4a files
What is the problem you are facing?
Funkwhale can only import Ogg Vorbis, FLAC, and mp3 files. Can we add AAC files to that? https://en.wikipedia.org/wiki/Advanced_Audio_Coding
What are the possible drawbacks or issues with the requested changes?
Is there a licensing issue that has prevented this feature from already being added?
