Add codecov to CI

[BenediktBurger]

Codecov seems to work even for other users forks.

This PR adds codecov (and probably removes the other one).

• It requires, however, the installation of the Codecov app on GitHub for the pymeasure organization? Here's the link: https://github.com/apps/codecov/installations/select_target
  @bilderbuchi can you do that, or just @cjermain ?
• And it requires to add a token to the repo secrets.
• Remove the old code coverage from the ci file and the README (badge)

Maybe it's useful for pymeasure as well?

I'm a fan of Codecov and used it for a recent project (rust-python-coverage). I've enabled Codecov for all PyMeasure org repos. I'll circle back on a token in the repo secrets. @BenediktBurger or @bilderbuchi , can either of you access the token creation through the PyMeasure org permissions?

I do not have access to the settings part of the pymeasure repos.

Thanks @cjermain for adding codecov

I've added the appropriate secret token to both this repo and pymeasure.

same here.

Thanks for adding this! I agree it could be useful for pymeasure, too.
