Correcting coverage calculations

[anilbey]

Description

As reported in #306, the python coverage reposting of efel was wrong. It was only detecting the test modules' coverage.

This PR corrects the coverage calculations for Python and also starts measuring coverage for C++. Efel is 58.7% C++ and
39.4% Python.

The whole list of changes include:

• Report C++ coverage
• Report Python coverage
• Integrate them to tox
• Integrate them via codecov
• Significantly faster tox test environment
• Move test module out of the deployed package to not to deploy tests and test dependencies
• Remove outdated repository files

Current status of coverage

We have ~%96 Python coverage and ~%41 C++ branch coverage.

Excellent!

[anilbey]

The old "test (3.7) Expected — Waiting for status to be reported" is blocking us from merging.

[anilbey]

@wvangeit the old test check is blocking it seems to be due to the branch protection rules https://github.com/orgs/community/discussions/26698#discussioncomment-3252954. Could you update them please?

If you'll merge could you also squash the commits this time? I created lots of revert commits while testing, they will look confusing in the git log I think.

[AurelienJaquier]

ok finally found how to remove the check. @anilbey it's good to be merged now ;)

Great, thanks @AurelienJaquier
