[PROBLEM] IR HAT power on/off - configuration

[TheOldPresbyope]

The vendor Wiki has neither schematic nor logic diagram for this board that I could find. That's what I mean by "I don't see an obvious way...." It could be as simple as a time-out circuit (likely) or something as complicated as a handshake-driven state machine (doubt it). Someone who has one will have to experiment.
