Since recent updates, either Openplotter, Signal K or even Pi I've lost my GPIO node/s.  
I get a "chip error" message.

1. Raspberry Pi 5
2. OpenPlotter 4
3. Signal K 2.30.0
4. Node.js 22.23.2
5. `gpiodetect` works
6. iiot2k GPIO nodes started reporting **chip error** after recent updates
7. Removed the package, but it is no longer available on npm (404)
8. `node-red-node-pi-gpiod` fails because `pigpiod` doesn't recognise Pi 5 (`unknown rev code d04171`)
