Add support for Python 3.12? (broken due to absence of `numpy.distutils`)

[agriyakhetarpal]

Looks like numpy eventually and finally removed distutils with Python 3.12+, which breaks the installation of scikits.odes.

Steps to reproduce

1. Install BLAS, C and Fortran compilers, etc.
2. Set the SUNDIALS_INST environment variable
3. pip install scikits.odes

Platform specifications

Operating system: macOS Sonoma Processor architecture: arm64 Python version: 3.12.0 Version of pip used to install: 23.0.1

Installing on Python 3.8–3.11 works fine, of course. Is there a plan to support Python 3.12 soon? I would have tried to do this in a PR but I am sure it would be very daunting to try an installation from source (probably the same though since PyPI has sdist and not pre-compiled binaries), plus the Extension and build_ext utilities from setuptools might not be able to handle the current packaging infrastructure present here: https://numpy.org/doc/stable/reference/distutils_status_migration.html#moving-to-setuptools.
