Convolution import error with setuptools v65.6.0

See original GitHub issue

setuptools v65.6.0 made a change in their bundled version of distutils, which is breaking the import of the compiled extension in convolution, which is done with numpy.ctypeslib.load_library (which depends on numpy.distutils). Some of our builds are failing (currently RTD and wheels, but it seems the tox based one are still using the previous version of setuptools, probably because virtualenv did not update yet):

Traceback:

Am I correct in the understanding that the long term answer he is that we need to stop using numpy.distutils ?
