Module riot_coap_handler_demos::gpio

A GPIO pin wrapped in a CoAP resource

This expresses the pins as a CBOR resource that’s true for high and false for low.

• There is nothing RIOT specific about this; maybe there should be embedded-hal-coap-demos?

  Probably not, as while now this only maps in and out pins, a future version could allow putting a configuration there as well, and that exceeds what embedded-hal can do.
