Problem with Python 3.11

[Paul-Wray]

Tried to setup and run examples. Exception with python 3.11.

I added default_factory, this should fix it. #7825b23

I just released a new version, can you try if it works with Python 3.11?

FYI, we're currently using pyelmer 1.2.1 with python 3.11 without issue. (so hopefully this can be closed!)
