I hope to add support for the door lock model: lumi.lock.mcn009.

• lumi.lock.mcn009 is a version of lumi.lock.mcn008 with an added camera.

• E20 WIFI version: https://home.miot-spec.com/spec/lumi.lock.mcn008

• E20 Cat Eye version: https://home.miot-spec.com/spec/lumi.lock.mcn009

• These two should be basically interchangeable, so I hope support for the device can be added.

• I don't know how to compile because I have no background in coding. I don't know where to start, but if there are relevant tutorials or guides, I can try to add the related configurations myself.
