Not sure how to go about the submodule update... it is needed, but you probably want to do it separately / to a specific commit?

I see I don't need to give guidance, as you found your way :-)

I updated the C core on main before I realized that you did it here as well. Latest commit is okay for now.

P.S. @ntamas is in charge of the python-interface, but he's very busy right now. If you have any questions, I'll try to answer.

@ntamas, when you are dealing with this PR, be careful: it's been from a fork of the main branch, trying to force-push could wipe out our main branch.

@GenieTim Could you please close this and open a new PR from a branch named differently than main? I only realize now why I wasn't able to push to this.
