[FR] Input GPIO to publish state via MQTT

[KoMa1978]

It would be great to have the possibility to configure a GPIO input and publish the state via MQTT and change another GPIO state.

For example a switch on GPIO 3 is closed, this should:

• change a published MQTT topic from value "A" to value "B".
• change configurable GPIO Pin to HIGH/LOW for a specific timeout (identical settings like HomeKey Auth Success/Failure)

I want to implement some kind of enclosure monitoring.
If someone opens the reader enclosure I want to be aware of it (via MQTT).
With the GPIO you can turn on a buzzer for a local alarm.

Can most probably be achieved with #243 ... or at least a very similar FR.

Thanks for reaching out, will think about that one
