[Unwrap] Prepare SequenceNumberUnwrapper for migrations

This is in prep for the migration of all unwrappers to
SequenceNumberUnwrapper as a standard implementation.

This moves the SeqNumUnwapper to its own header and adds 2 methods to
SeqNumUnwrapper which are defined by other unwrappers:
* PeekUnwrap
* Reset

It also adds two implementations for RtpTimestamps and
RtpSequenceNumbers.
