FLAC downloads

It's currently not very clear how I'd go about downloading FLAC versions (if available), from the looks of it, the code does try to check if FLACs exists, but I don't think it actually works.

I've written my own version from scratch since none seem to work properly on here.
Supports AAC, Opus, FLAC, and MP3. I need to test a bit more, so It'll be up in a few hours.
