ENH: Configure LoRa module baud rate in hub code setup() #59
Description
An out of the box LoRa module defaults to 115,200 baud. Right now, this must be changed to 38,400 baud using an FTDI module. The setup() code could be enhanced to test the baud rate and if it is 38.400, skip reconfiguring it, but if it is 115,200, change it to 38,400 and confirm.
