Parsing multiple-packet rtcp-rsize fails about rtcp HOT 3 CLOSED

@maxhawkins i really like your solution. Should the user call CompoundPacket.Validate themselves, or should it get called by pions/webrtc? should there be an option that gets set somewhere?

from rtcp.

rtcp-rsize is negotiated out of band so there's no way to know if you're in RFC 3350 mode or RFC 5506 mode.

I suppose you could have something like

type Unmarshaler struct {
  ReducedSize bool
}

and then Unmarshaler{false}.Unmarshal(...). Not sure if that's worth it.

What were you thinking?

from rtcp.

Maybe we should leave that out of pions/rtcp, and let downstream deal with deciding whether to validate. I guess pions/webrtc knows whether it negotiated rtcp-rsize or not, and therefore it's responsible for the validation, but i'm really not sure about that
