Should we specify generic FEC for audio as well as video? Opus has built-in
FEC, but it only works for the SILK portion of the payload, meaning that in
high bitrate situations, it won't do much for you. I don't know if it has
benefits over generic FEC.

Some application providers have mentioned that FEC helps with audio
intelligibility on cellular networks, so I think this is important to
support.
