Relying on now-deprecated APIs in setuptools/NumPy

[RhysU]

Someone noticed the following sea of deprecation issues:

$ PYTHON=python3 make ar.so
python3 setup.py build_ext --inplace
/usr/lib/python3/dist-packages/setuptools/installer.py:27: SetuptoolsDeprecationWarning: setuptools.installer is deprecated. Requirements should be satisfied by a PEP 517 installer.
  warnings.warn(
/home/rhys/Build/ar/.eggs/setuptools_scm-8.1.0-py3.10.egg/setuptools_scm/_integration/setuptools.py:31: RuntimeWarning: 
ERROR: setuptools==59.6.0 is used in combination with setuptools_scm>=8.x

Your build configuration is incomplete and previously worked by accident!
setuptools_scm requires setuptools>=61

Suggested workaround if applicable:
 - migrating from the deprecated setup_requires mechanism to pep517/518
   and using a pyproject.toml to declare build dependencies
   which are reliably pre-installed before running the build tools

Some of them may just be my weird setup. But the NumPy one definitely merits a code chage.
