Bug Report

I had to install the latest version (0.3.0) of libnl from PyPi; without it, wifi-survey failed immediately with

$ wifi-survey help
Traceback (most recent call last):

pip install libnl installs libnl0.2.0, which still does not work - needs to be `pip install libnl3.

Even with libnl3 installed, scancli.py offers up this error

scancli.py isn't mentioned in the README, but I was looking for somewhere to get the version info - I don't seem to have 1wifi-survey-heatmapand the other commands do not have a--version` flag.

@DL6ER Is there a chance that you have a few minutes to look at this? I believe this is related to the improvements that you contributed in #4.

ModuleNotFoundError: No module named 'libnl'

Apparently, the upstream project libnl still hasn't merged my fix for python3.6+ compatibility. More information in this pull request: https://github.com/Robpol86/libnl/pull/29

@erik-overdahl Please try installing my fixed version of libnl using pip3 install --upgrade --user git+https://github.com/DL6ER/libnl

@jantman Sorry, I really assumed they'd merge the fix in. We may have to add this to the README if it works.

The endpoints defined in setup.py work now but scanclii.py is still broken if called directly

created a new venv "test2", then python setup.py develop before this output:

This should be fixed with 1.0.0 which was just released. Please feel free to re-open if it hasn't been.
