Add GitHub Action to run the tests on pushes and pull-requests

Once #730 is resolved, add a GitHub Action to run the tests to prevent them from breaking.

I'm thinking of running on pushes and pull requests to master and develop to start with. Could then add bugfix/* perhaps?

Actually I just merge to master if I'm doing a new release with the release branch.
I think the develop branch aswell as maybe a bugfix or feature branch is the most used here.
But I think the best we could start simple and as more contributors come, we can then make more rules?

But anyway I like the idea to have automatic runs :)

Successful run in develop!
