move a function that creates and sends a sdp_message to the Transceiver
The only remaining external method that creates an sdp_message and uses the Transceiver to send it.
is:
DataSpeedUpPacketGatherMachineVertex._determine_and_retransmit_missing_seq_nums
which is interesting as every other time that code uses its own connection to send the sdp message
