dependency to deprecated `setuptools.command.test` breaks installation

[ShapingView]

Hello,

installing numpy-stl from source breaks our pipelines. This is due to a dependency to setuptools, which removed a long deprecated function: https://setuptools.pypa.io/en/stable/history.html#v72-0-0

I could reproduce this locally using pip download:

pip download --no-binary :all: numpy-stl                                                                                                                                                                                                                                                                           1 ↵

We are actually using an older version, where this is also the case

[notice] A new release of pip is available: 23.3.1 -> 24.2

This seems to be an issue for many packages now: https://github.com/pypa/setuptools/issues/4520

But the command is deprecated for 5 years, now.

As of now, I used this hotfix, but a better solution would be specify build-dependencies within the numpy-stl package.

echo "setuptools<72" > pip_constraints.txt
export PIP_CONSTRAINT=pip_constraints.txt

It's silly really... I removed the code that was using it a long time ago but it seems I forgot to remove the import :)
