numpy.distutils not compatible with python version>=3.12

[nmiller95]

Hi! Tried to install ellc in python 3.12 and it failed since numpy.distutils has been removed for the newest python versions - https://numpy.org/doc/stable/reference/distutils.html. It still imports OK in a v3.11 environment but might need attention soon!

I also got the same failure when installing ellc in python 3.12. It would be good to fix this version incompatibility issue.

Thank you for making this significant update, @zhang-zhixiang! I have tested it on my M4 Mac Mini with Python 12, and it works perfectly. It should also work for other M-series chips (M1, M2, and M3).

The general installation procedure for Mac with M-series chips is as follows:

### Install gfortran via Homebrew
brew install gfortran

### Install the latest version of ellc (now, it is 1.8.11)
pip install git+https://github.com/pmaxted/ellc.git

And, @pmaxted, if you need me to perform any additional tests, feel free to let me know!

Best,
