Broken with setuptools 59

[mdavidsaver]

I received an email report from a user encountering the following error with py3.10, setuptools 59.6.0, and setuptools_dso 2.11. His issue was resolved by updating to setuptools 75 (also works for me with 66).

I think this indicates that setuptools_dso 2.11 is broken for setuptools at some point between 66 and 59.

I am inclined to treat this as a "won't fix".
