Set Bindkey for Xiaomi CGDK2
Copyright: Aaron Christophel / Atc1441 https://ATCnetz.de
Modified by Zaluthar to support setting the bindkey for Xiaomi CGDK2, for method see ESPHome Xiaomi BLE site.
The only functions setup and tested are 'Connect', 'Do Activation' and 'Mi Bind Key'. Warning: The new bind key will work with ESPHome, but the Mi Home app will not recognise the sensor anymore once the device has been activated by the TeLink flasher application. To use the sensor again with the Xiaomi Mi Home app, the device needs to be removed and then re-added inside the Mi Home app.
Please select a .bin file you want to flash to a Telink BLE device.
