I wrapped and nimified [libgpiod](https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/about/). Tested on Rpi2. I could not wrap the iterators, #define-d in C as macros... but, for me, it is not a big problem ;) [https://github.com/nais314/nimgpiod](https://github.com/nais314/nimgpiod)
Happy Holidays and Happy New Year to All!
