`pint` is broken on python 3.13 #11

I believe there is an import failure with bw2data in a python 3.13 environment. I tried installing both 4.0.dev59 and 4.0.dev56.

import bw2data as bd returns TypeError: cannot inherit frozen dataclass from a non-frozen one. The error message seems to point to something in Python 3.13.

Downgrading python solved the issue.

This is a problem in pint. If it continues we will update bw2parameters to make pint optional.
