Create separate GitHub action python-linters (#236)

separated the lint build from tests builds, linters will now not run on every python + LXML version, which does not make any sense anyway (and is currently breaking builds for py 3.7 due transitive dependencies conflicts).

passing tests and passing linters are still mandatory for PR, but now the pip install dependencies configuration is easier to satisfy on the linter side + saving a bit time.
