Publishing package to pypi fails.

[OrangeTux]

The GA workflow to publish the package to pypi fails.

The issue is that the README.rst is not valid. One can check it's validity using:

$ python3 -m pip install build, twine
$ python3 -m build --sdist
$ twine check dist/*
Checking dist/ocpp-1.0.0.tar.gz: FAILED
ERROR    `long_description` has syntax errors in markup and would not be rendered on PyPI.
         line 62: Warning: Title underline too short.

         Charging Station Management System (CSMS) / Central System

For more information, read We should fix the issue and modify our GA workflow to prevent this issue from happening again.

• https://packaging.python.org/en/latest/guides/distributing-packages-using-setuptools/#packaging-your-project

After the fixes, I suggest we create a v1.01 release
