Feature request: Add support for reading the state from Switchbot devices

[moretea]

Based on the observed behavior in the Switchbot app, it must be possible to query for the current state from the Switchbot devices.

I'm not intimately familiar (yet) with BLE, but from what I gather, we could fetch these as characteristics. This poses the question of the impact on battery life if we poll to often.

I have succeeded reading the battery, position and light level using the python package bleak. The bluepy package is not working for me, it does not fetch any advertisement data regarding battery, position or light level. I'm new to bluetooth communications, so I might have done something wrong using bluepy. I also like bleak more, since it works cross platform, whereis bluepy only works on Linux. I probably will start building a similar setup, using bleak.

Hi, I'm really keen on trying this additional functionality out. Any chance you are willing to make a new release containing it?
