EvtBatteryStatus missing in aioflic.py

[dleffo]

I added this to the end of _dispatch_event from fliclib.py and added entry for bd_addr. It seemed to do the trick:

if event_name == "EvtBatteryStatus":
         listener = self._battery_status_listeners.get(items["listener_id"])
         if listener is not None:
                bd_addr = listener._bd_addr
                listener.on_battery_status(listener, bd_addr, items["battery_percentage"], items["timestamp"])
