Minimal Windows CI with GitHub Action

[rhysd]

Related to #90

Hi,

This PR adds a minimal Windows CI with GitHub Action. It only runs unit tests and takes coverage with Python 3.8.

Here is an example of CI result:

https://github.com/rhysd/covimerage/runs/416425706?check_suite_focus=true

Currently several tests fail but I don't know the failures are due to #90.

Do unit tests run with tox require vim or nvim editor command? Currently they are not installed. Please let me know if they are necessary. I'll add step to install them.

EDIT: If you want to put a CI badge for this in README.md, please let me know. I'll do.

I also added Python 3.5, 3.6, 3.7. 3.4 is not supported by setup-python action.

I fixed 21 failures but 4 failures are remaining. They look hard for me to fix since expectations are not clear for me.

And there are a few test failures which may be related to #90.

'Better Code Hub' CI fails but I don't have permission to see the results.

Thanks, this looks good!
(sorry for the late response also)

Do you want to update it with regard to the token?
Otherwise I can also do it myself.

[blueyed]

I'd prefer to use the installed/stable pip. Not that important though for now.

[blueyed]

Done.

You can ignore it, it's just an experiment.

I can look into them during the next days.
I plan to spent some time for coverage 5 support here anyway soon.
