* (to prevent unneeded retransmissions), we want routing messages to be sent next,
* then messages marked as reliable and finally 'background' packets like periodic position updates.
* So I bit the bullet and implemented a new (internal - not sent over the air)
* field in MeshPacket called 'priority'.
