scipy._build_utils is no longer available in scipy 1.10+

[boegel]

The scipy._build_utils used in setup.py is no longer shipped in scipy 1.10+, which leads to:

No module named 'scipy._build_utils'

This can be easily fixed by making the following change in setup.py:

# hardcoded value, used to be imported from scipy._build_utils (which is no longer available since scipy 1.10)
numpy_nodepr_api = dict(define_macros=[("NPY_NO_DEPRECATED_API", "NPY_1_9_API_VERSION")])
