Add note about the voltage sensor

(small square body, segment LCD, broadcasts temperature and humidity once in about 10 minutes and battery level once in an hour (original firmware). With the original firmware, advertisements are encrypted, therefore you need to set an encryption key in your configuration, see for instructions the [encryption_key](#encryption_key) option (not needed for sensors with custom firmware).
- `ble_monitor` also supports custom ATC firmware (both the firmware by `ATC1441`, available [here](https://github.com/atc1441/ATC_MiThermometer), and the improved firmware by `pvvx` available [here](https://github.com/pvvx/ATC_MiThermometer)). Both custom firmware's broadcast temperature, humidity, battery voltage and battery level in percent. For the `pvvx` firmware, it is advised to change the setting `advertisement type` from `all` to `custom`. Sending multiple advertisment types at the same time might cause the voltage sensor from not showing up, depending on which advertisement comes first. The advertisement type `custom` will also result in a higher accuracy. Reloading the integration is needed to receive the voltage sensor after switching the firmware)
