add github actions support

[linuxmaniac]

As mentioned at #62 project needs to migrate CI to github actions

[linuxmaniac]

@goodboy I would love to see the project improve the actual situation. So, lets start with implementing the CI

[goodboy]

@linuxmaniac thanks for the the PR!

Do you have an example of this CI run working fully on your fork by chance?

Ok so maybe to just get this all going can we skip the test_confpy_hooks test which seems to be the common failure and then possibly also unrap the suite from using tox.

If you're uncomfortable try that lmk 😸

[linuxmaniac]

@goodboy with this last version, all OK

https://github.com/linuxmaniac/pysipp/actions/runs/3599894859

[goodboy]

@linuxmaniac nice work, maybe make a followup issue for those tests as well so we don't forget about them 😂
