PEP 440 - the format for the versioning in this package does not have support in new versions of pip

[Cpapa97]

Notice from a slightly older version of pip (0.22.x):

/usr/lib/python3/dist-packages/setuptools/dist.py:507: UserWarning: The version specified ('ibl_1.3.0') is an invalid version, this may not work as expected with newer versions of setuptools, pip, and PyPI. Please see PEP 440 for more details.

On newer versions (>=0.23.x) it does not install or allow you to create an sdist failing with a hard error.
