Mathieu Duponchelle d12d45db77 reddec: implement support for the BUNDLE case
When multiple streams are bundled together, there may be more
than one red payload type to handle.

In addition, as the red decoder works by filling in gaps in
the seqnums, there needs to be one rtp_history queue per sequence
domain.
