Implement a "seen packets" table to track packets that have already been processed by the serial bridge. This prevents packets from being re-transmitted over the serial link if they have already been seen, and it stops inbound packets from serial from being re-injected into the mesh if they are duplicates. Duplicate inbound packets are now freed to prevent memory leaks.
