Add support for Xiaomi sensors

[ruippeixotog]

(previously zigpy/bellows#43)

The protocol used by Xiaomi to connect to their sensors seems to deviate slightly from the ZigBee standard, preventing zigpy from communicating properly with them. It would be great if we could use a generic ZigBee radio to connect Xiaomi sensors to Home Assistant.

"slightly"...

@ruippeixotog does this include the smart wireless switch? https://xiaomi-mi.com/sockets-and-sensors/xiaomi-mi-wireless-switch/

Can we close this issue? It seems to work well enough now.

This seams to be fixed in PR #45.

I'm not sure if this is fixed yet. From the commit history it looks like this fix is in 0.1.0, which is what's running on my hass.io instance, but I still get the following error when adding a v2 Xiaomi motion sensor:

Attempting to re-pair the device does show the Device xxx left the network message, followed by a rejoin, then either the above error or sometimes:

I have the same issue, I opened #61 to track it.
