Add yang-cli
The original idea for this was that I would libyang C++ bindings for
this. Unfortunately, there have been problems with them as explained
here: https://github.com/CESNET/libyang/issues/1106. The easiest
solution to this was to just use the C api of libyang. After creating
some safe wrappers around pointers, it wasn't too difficult.
