[GPIO] New GPIO Binding for OH3

Hi @nbauer
This is great! thanks for sharing this.

I use pigpio as a replacement for lirc. My usecase is something like i documented here
In summary, i use the irrp.py file as detailed on the page here and pass a series of on/gap/off codes to simulate an IR remote for my air conditioner. In the backend its using pgipiod.

If i understand correcty, at the moment the binding sends or receives a unitary on signal which it writes to the switch. Is there any possibility to extend this to mirror the functionality of the irrp.py file?

thanks in advance.
