Module message_lane_loop

Message delivery loop. Designed to work with messages pallet.

Single relay instance delivers messages of single lane in single direction. To serve two-way lane, you would need two instances of relay. To serve N two-way lanes, you would need N*2 instances of relay.

Please keep in mind that the best header in this file is actually best finalized header. I.e. when talking about headers in lane context, we only care about finalized headers.
