-CircuitPython RFM69 packet radio module.  This supports basic
-RadioHead-compatible sending and receiving of packets with RFM69 series radios
-(433/915Mhz).  Note this does NOT support advanced RadioHead features like
-guaranteed delivery--only 'raw' packets are currently supported.  In addition
-this is NOT for LoRa radios! Finally be aware this is a 'best effort' at
-receiving data using pure Python code--there is not interrupt support so you
-might lose packets if they're sent too quickly for the board to process them.
-You will have the most luck using this in simple low bandwidth scenarios like
-sending and receiving a 60 byte packet at a time--don't try to receive many
-kilobytes of data at a time!
