Version 1.0.2 only in Git, 1.0.3 only on PyPI

[nils-werner]

There is a slight version mismatch between this repo and PyPI:

1.0.2

• exists in this repository
• does not exist on PyPI

1.0.3

• does not exist in this repository
• exists on PyPI

I added a git+ link to my pip dependencies because there were no recent versions of cart on PyPI back then. Now I am stuck with a package from git (which was 1.0.2) that I cannot upgrade to PyPI.
