Allow nnef_tools pip install from git

[idenc]

Allowing to install nnef_tools package with the command pip install git+https://github.com/KhronosGroup/NNEF-Tools.git would be very convenient. +

Currently I get this error:

(venv) >pip install git+https://github.com/KhronosGroup/NNEF-Tools.git

Command "python setup.py egg_info" failed with error code 1 in C:\Users\iden\AppData\Local\Temp\pip-req-build-s_8ugsgs\

Which looks like the shutils.rmtree is failing. If you guys could take a look at this I would appreciate it.
