`pip install -r requirements/3.x.txt` fails

Describe the bug

I tried running pip install as per Readme.
I get error

Collecting codecov==2.1.12
  ERROR: Could not find a version that satisfies the requirement codecov==2.1.12 (from versions: none)
ERROR: No matching distribution found for codecov==2.1.12

Apparently codecov have changed some things around and have taken the codecov package off PyPI completely!
Related: codecov/python-standard#31

To Reproduce

Follow readme instructions on a fresh virtualenv

Runtime environment

Thanks for noticing. Fixed in #332 and should work on master.

Oh right yes I noticed this yesterday but only reported today. Apparently you're eliminating bugs quicker than Lucky Luke his shadow 💪

Ha, I wish!
