RTP Over QUIC (RoQ) stack (headers)

Implementation of the RTP Over QUIC (RoQ) stack as part of the library itself. At the time of writing, this implements (most of) version -10 of the protocol.

Note

This is the internal implementation of RoQ in the library. You're still free to only use imquic as the underlying QUIC/WebTransport library, and take care of the RoQ implementation on your own instead: in order to do that, use the generic imquic client/server creation utilities, rather than the RoQ specific ones.
