Adds the types and methods required for sending and receiving data channel messages over the media transport. These are: - A DataMessageType to distinguish between text, binary, and control messages - A parameters struct for sending data messages, which specifies the channel id, type, and ordering/reliability parameters - A sink for data-channel related callbacks (receive data, begin closing procedure, and end closing procedure) - A method to set the sink for data channels - Methods to open, close, and send on data channels These methods, combined with the state sink, allow PeerConnection to implement the DataChannelProviderInterface using MediaTransport as the underlying transport.
