Should we skip the whole module?

pytest.skip(reason, allow_module_level=True)

Doesn't matter, it will still fail.
The main issue right now is, that the test module imports the dsmr_parser module via the integration, which imports PyCRC, which is missing on PyPi.

[frenck]

• Disabled tests in pytest as a module
• Commented out the import from the component, to prevent it from crashing because of the missing package.
• Disabled pylint/flake8 on the place it used the commented out import.

This all ain't pretty, but IMHO the alternative is removing it completely.
