MAINT: Support Python 3.12

[larsoner]

This isn't a good fix, but numpy.distutils is gone in Python 3.12. This should at least allow it to build in non-editable mode.

Thanks @larsoner! What would be the best way to do this while supporting editable builds?

[larsoner]

Not sure. And several variants of what I have here do not seem to work, e.g. the patches used here:

https://github.com/conda-forge/mayavi-feedstock/pull/77

I think in theory the right move here is to migrate to using setuptools directly instead of anything numpy.distutils-related. But I'm not sure how trivial that will be...

To support Python3.12. We should be noted whether vtk's 9.3 will be compatible with Python 3.12. https://pypi.org/project/vtk

Probably not on PyPI but conda-forge has it already, which triggered https://github.com/conda-forge/mayavi-feedstock/pull/77. See

• https://github.com/conda-forge/vtk-feedstock/pull/316
• https://anaconda.org/conda-forge/vtk/files

I haven't tested it locally but I would be surprised if it did not work.

@larsoner -- many thanks for this. Sorry for the delay in merging this.
