[RELEASE] Ring Alarm Range Extender Gen2 driver

[dennypage]

I've just pushed a minor update to the driver (1.3.0) to cover the situation of the power source (mains/battery) and battery state changing while the hub is down. This addresses the issue described here:

@672southmain

when a power fail occurs and the hub shuts down, and then later reboots when power returns, the Ring Extender switches from battery to mains before the hub has rebooted, causing the “switch to mains” event to be missed (discarded), so the Ring Extender’s power source state in the driver still indicates that power source is “battery”.
