Add pre-commit config + update eslint

Should fix: https://github.com/cytoscape/ipycytoscape/issues/299

@marimeireles do you think the instructions on usage are through enough? I can add more - could also imagine adding instructions for what to do once the bot pushes to your PR.

I expect the checks to fail as this repo has some flake8 issues (which we could ignore by removing the flake8 check)

oh boy:

The failing test is one that was actually never being run before and that I discovered wasn't being due to the flake8 checks. Confused by the python version dependency though

[marimeireles]

This is such a weird error 😅 Can't reproduce it locally What's up with these CIs

[marimeireles]

I reran the test and now another python is unhappy for another weird reason.

I did a bit of experimenting on https://github.com/jenshnielsen/ipycytoscape/pull/4 and it looks like the test failure can indeed be reproduced by only renameing the second test_add_edges to avoid collisions. It may be worthwile extracting that from this pr marking it as xfail and then merge the rest of this and fix it in a subsequent pr ?

308 should resolve the test issue while still running all the tests
