Preventive maintenance of package

[alanverresen]

At the moment, it is unclear how this package is being maintained. Everything still seems to work like it should, but there currently aren't any efforts for preventive maintenance to make sure that it stays that way. For example the current tox setup only runs tests for versions of Django that aren't supported anymore.

I'd be happy to help and send a pull request to fix this, and would also like to help in any other way that I can. Can you point out any other parts that I probably also need to take a look at?

If you'd like to update the tox.ini that'd be nice for others, the most important thing to update would be the GitHub actions test.yaml, appreciate the offer.

I started working on updating the GitHub actions and tox, but it has turned into somewhat of a complete overhaul. Can you give some feedback on the following things:

• Are there any particular changes so far that you don't like or have questions about?
• It seem like you were testing with multiple databases at some point, but it wasn't working with tox/GitHub actions anymore, so I temporarily dropped that part. My next step is to add that back in.
• Was there a particular reason for using the ./test_run.sh script over an alternative testrunner? It doesn't seem necessary (anymore), but maybe I'm missing something? I'm planning on changing some parts of it, so I don't want to break anything that's not immediately obvious.
