wireprotov2: handle sender protocol settings frames
We teach the server reactor to handle the optional sender protocol
settings frames, which can only be sent at the beginning of frame

Right now, we simply decode the data and record the sender protocol
settings on the server reactor instance: we don't yet do anything
meaningful with the data.
