support node-red-node-pi-gpiod

[janvda]

Currently there are 2 different nodes to interface with the raspberry pi hardware (GPIO pins):

• node-red-node-pi-gpio
• node-red-node-pi_gpiod

This issue is raised to support the 2nd node (=node-red-node-pi_gpiod) to interface with the raspberry pi hardware. This node can easily be installed via the node-red editor (via the manage palette menu) but in order to use this node the daemon pigpiod must be running.

So this issue is about how to get the daemon pigpiod running.

So this issue is about how to get the daemon pigpiod running.

I think that the best way (using balena) is to create an extra docker service that runs this daemon.

I have managed to create this service (see service pigpiod in my branch https://github.com/janvda/balena-node-red/tree/pigpiod) but it still has issue janvda#1
