[App][Pro] OCPP Server - Run any OCPP 1.6 EV charger from Homey

@nogren

Thanks so much for this app! It will allow me to move away from the cloud based NexBlue app to local control.

Although I am new to this and may have missed something, I do have a question: Why is there an 11kW maximum on set target power? Does the OCPP get this from the charger or is it hardcoded?

I have a 25A circuit so I could do 16kW charging (some cars have a 22kW OBC).
Perhaps an option to set the maximum allowed in the app?
