Compatibility issue when building with python=3.12

[Liwen-A]

When I tried to build the project on an EC2 instance with intel icelake x86, ubuntu 24.04, I encountered the following error when running python setup.py install

Installed /usr/local/lib/python3.12/dist-packages/pycryptodomex-3.19.1-py3.12-linux-x86_64.egg

  `numpy.distutils` is deprecated since NumPy 1.23.0, as a result
  of the deprecation of `distutils` itself. It will be removed for
  Python >= 3.12. For older Python versions it will remain present.
  It is recommended to use `setuptools < 60.0` for those Python versions.

error: Cython needs to be installed in Python as a module

I was able to solve the problem by specifying the following version for numpy and pmgy2 in setup.py:

numpy ≥ 1.26.1
gmpy2==2.2.0a1

Thank you, @Liwen-A ! The compatibility issue arises because we are attempting to support Python 3.8 and above. However, it appears Python 3.12 requires additional support. We will work on fixing this issue. Thank you for your feedback.
