nit: Should we have audio/mp2t as well? I'm not sure how common audio-only
transport streams are.

I prefer not to include it until there is a relevant use case.
Currently, audio only HLS relies on a list of aac or mp3 files, so it doesn't
use TS in that case.
I don't have a use case in mind right now.
