ATC mi-thermometer binding key is missing

[rafacouto]

The problem

LYWSD03MMC devices can be flashed with the ATC firmware and it also uses a bind key (like the original firmware) but esphome doesn't implement the bindkey attribute with the atc_mithermometer platform. It is convenient to use this bindkey as a basic security feature (crypted communications and OTA upgrades of the device).

2022.12.8
