KNX: add state_address to expose feature

Hi,
it would be nice to be able to expose an address and state_address to the KNX bus from the KNX integration.

This could allow us to expose a media player to the KNX bus and toggle the power state (while keeping the state of the object on the bus as well) as an example.

Maybe there is already a way using templates, but right know I didn’t find a way to keep all the information in one object.

Keep up the great work

You can always use a switch for this. Toggle it maybe with an automation.
Or a combination of Sensor / binary_sensor and expose sensor.

Thank you very much, now I got it working.
