Missing comma in setup.py? "six>=1.12.0<2"

[kjcole]

I don't write setup.py files much, but I think there's a comma missing:

$ python3 setup.py install --user
error in simplify-docx setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Expected end or semicolon (after version specifier)
    six>=1.12.0<2
       ~~~~~~~~^

Methinks it should be six>=1.12.0,<2: a comma betwixt the version criteria.
