imp package is removed from python 3.12

[h-oll]

Pantalaimon cannot be installed on systems with python 3.12 as it references the imp package that has been removed and replaced by importlib.

Sorry for the delayed response @h-oll, thanks for the report! I will check that out later today and get that fixed! Or if you feel like it, feel free to open a PR and I can review it later as well.

@h-oll Can you give a bit of information on how you installed the package? I just built master from source by creating a new conda environment and running pip install . and it was able to build just fine. I also don't see any reference to the imp package anywhere in the repo so a full stack trace would be helpful.

Looks like this happens because an old version of matrix_nio is installed. I'm able to run pip install matrix_nio==0.25.2 which makes that error go away, but warns of a compatibility error (does not affect anything it would seem). I arbitrarily picked 0.25.2, you could probably use the newest version just fine

@RedChops Thanks for the info! I opened a PR with the updated version of matrix_nio and will merge that tomorrow if there aren't objections.

Fixed with #178!
