Merge #200 broke Windows AFC service functionality

[Starwarsfan2099]

Test environment

• Windows 10
• iPhone 12 (iOS 14.3)

Describe the bug
Merge #200 broke some Windows functionality, specifically connecting to a device via AFC. The new way of performing ls uses pygnuutils. pygnuutils requires the package fcntl which does not support Windows. Windows support has been great for me at least until this change.

To Reproduce
Steps to reproduce the behavior:
python .\tests\services\test_afc.py

Expected behavior
Expected a succsesful test.

Thanks for the report! I created a PR that fixes the issue but in a somewhat patchy way. I discussed with @matan1008 and he plans to add windows support for pygnuutils so this is just a quick solution for the meantime.

Can you verify the PR solves the issue on your setup?

The PR does solve the issue on my setup! Thank you!

pygnuutils now has windows support.
Can you verify once more this PR solves the issue? you should now have full ls capabilities on windows within AFC. If so, I'll publish this release.

I have verified this PR solves my issue on Windows and is still functioning perfectly on Linux. Thank you!

Thanks again for the report and testing :). I've merge this change and published a new release with the solution:
https://github.com/doronz88/pymobiledevice3/releases/tag/v1.16.1

We also modified the github CI script to include test installation on windows-latest so such things won't break again.
