Proposed solution

See https://setuptools.pypa.io/en/latest/pkg_resources.html as instructed

Similar to #144, this is coming from diffpy.utils

[sbillinge]

Odd, that should have been fixed by cookiecutter I think? Ok o fix manually but nice to understand why it want caught in the cut....

[bobleesj]

@sbillinge somehow my local mac installed an older version of diffpy.utils with python 3.13

I think installation issues will be removed once we release diffpy.utils supporting 3.13

[bobleesj]

I will close this issue once we have a brand new diffpy.utils

[bobleesj]

Closing since it correctly installs the diffpy.utils (3.5.0) supporting py.3.13
