Driver support for AstroLink 4 Pi

[wannabecoffeenerd]

Using indigo sky on a Raspberry Pi is very nice, but it would be even nicer to use it on an all-in-one device like the AstroLink 4 Pi. This is based on a Raspberry Pi compute module, so everything should work out of the box, but it would be great if the drivers for focuser controller, switchable power outlets, etc would also be available as an indigo driver. There is an indi driver, not sure how hard it would be to port that over to an indigo driver: https://github.com/astrojolo/astrolink4pi.

If this is something that is interesting to the indigo devs, I'm happy to take on some of the driver porting work if I can get some pointers on what exactly needs to be done.
