This reverts commit 9d0730942677a520ce7e184d081b4c5a2469fc48.
Reason for revert: Speculative revert due to failing downstream test. If the test recovers, I'll assign the issue to the tests owners.
Original change's description:
> red: generate and parse the red fmtp format
>
> generates a fmtp line like
> a=fmtp:<red payloadtype> <opus payloadtype>/<opus payloadtype>
> and matches the incoming redundant payload types against the
> send codec one. Offers without an FMTP line will not use RED.
> Redundancy levels of 1 (plus main packet ) to 32 are accepted but
> this is not wired up to the encoder since the O/A semantic of
> RFC 2198 is not clear.
>
> This decreases the chance of a collision with the SATIN codec
> which also runs on 48khz (but so far does not specify a channelCount of 2)
