* The following method (startAirPodsScanner) creates a bluetooth LE scanner.
* This scanner receives all beacons from nearby BLE devices (not just your devices!) so we need to do 3 things:
* - Check that the beacon comes from something that looks like a pair of AirPods
* - Make sure that it is YOUR pair of AirPods
* - Decode the beacon to get the status
*
* <p>
* After decoding a beacon, the status is written to PodsStatus so that the NotificationThread can use the information
