Does numpydoc need to be an install_requires dependency?

[rly]

I work on a package that uses skan and am trying to reduce the dependencies that are installed. I see that setup.cfg specifies that installing skan requires the numpydoc package:
https://github.com/jni/skan/blob/main/setup.cfg#L54

numpydoc does not seem to be important for using skan. Does it need to be under install_requires? Can it be moved to the docs key of the [options.extras_require] section below?

Interestingly, the version of skan on conda-forge does not require numpydoc:
https://github.com/conda-forge/skan-feedstock/blob/main/recipe/meta.yaml

Oops! Yes that seems to be an oversight. I'm not sure why it went there in the first place rather than [docs]. Would you like to/be able to submit a PR fixing this? Thank you! 🙏

I just looked a little more closely at this and realized that numpydoc does not seem to be used at all. In 2f806e7, the last reference to numpydoc was removed from the codebase. Should it just be removed? I also see that it is not in any of the requirements files: https://github.com/jni/skan/tree/main/requirements

😂 yup! Thank you for spotting all these oversights. 🤦
