New release for Python 3.13 and Biopython 1.85, dropping support for Python 3.9

[BjornFJohansson]

I think we should have a release supporting Python 3.13 and Biopython 1.85. There seems to be a problem with Biopython on Windows.

All good!

We should fix tests for python 3.13 it seems. Do you know what's going on? Seems like it may have to do with numpy

Also we should probably run the linters in all test files at once, otherwise every time we make a change in the test files the actual change gets buried in all the styling. Will create an issue.
