Support for /sys/class/gpio? #30

Hi,

Any chance to support /sys/class/gpio under Linux (like most SBC boards have)?

Or via some USB dongle:

Up-to-date approach would be /dev/gpiochipX

I'd certainly welcome contributions like this -- would be great to have the POSIX Snek also able to drive peripherals! If someone wants to give this a try, I will help anyway I can.

I’m not a C dev but I’ve seen wiringpi used as an abstraction for GPIO. The developer hung his gloves because of bad redistributors, but the library can still be installed (and is kept functional by the community), so it could still be a good option.
