Detailed background on this field:
I noticed a funny side effect of lora being so slow: Usually when making
a protocol there isnt much need to use message priority to change the order
of transmission (because interfaces are fairly fast).
But for lora where packets can take a few seconds each, it is very important
to make sure that critical packets are sent ASAP.
In the case of meshtastic that means we want to send protocol acks as soon as possible
(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.
And the transmission queue in the router object is now a priority queue.
