Article on wrapping C libraries in Nim

[adokitkat]

Hi! I necessarily don't want to create a new separate project if you're open to 
change up nesper. I was not aware of `cimporter` either. I don't quite like 
that futhark bundles everything to one file as well. To be fair I just 
experimented with futhark and I'll try cimporter next. Maybe we could contact 
each other and I could try to help you with wrapping ESP-IDF / nesper 
(hopefully) if you're open to it.
