nRF CircuitPython boards will now provide the file transfer service defined here: https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer USB capable boards will only advertise if previously bonded to a device or if the reset button is pressed during the fast blue flashes on start up. When pressed, the board will restart again but the blue period will not flash. Boards without USB will always advertise. When previously bonded, the advertisement is private so that no other peers can connect. If advertising publicly, the tx power is lowered to reduce the likelihood of bonding from a distance. This PR also fixes issues with loading identities of bonded peers so that our address can now be resolved and we can resolve others' addresses when scanning.
