[Feature request] - Installation with latest python version 3.13.1

[AlbertoMilocco]

Is your feature request related to a problem? Please describe.
Upgrade of my Gentoo system (kernel 6.6.67) and packages (Python-3.13.1_p1); installation of current version of Jade.

Command:

pip install -e ./

Outcome:

Preparing metadata (pyproject.toml): finished with status 'error'

Verbose log (extract):

Link requires a different Python (3.13.1 not in: '<3.13,>=3.9'): https://files.pythonhosted.org/packages/78/23/f78fd8311e0f710fe1d065d50b92ce0057fe877b8ed7fd41b28ad6865bfc/numpy-1.26.1.tar.gz (from https://pypi.org/simple/numpy/) (requires-python:<3.13,>=3.9)
Collecting numpy<=1.26.4 (from f4enix>=0.8.1->jade==3.1.0)

Describe the solution you'd like
Allow installation of Jade with most recent python versions.

Describe alternatives you've considered
Rolled system back to python slot 3.10

Additional context
Next, upon running jade and folder initialization, got an error that may be linked to system or python:

File "/home/alberto/wrk/f4e/JDev/Code/jade/unix.py", line 30, in
f = open(os.environ["MODULESHOME"] + "/init/.modulespath", "r")
File "/usr/lib/python-exec/python3.10/../../../lib/python3.10/os.py", line 680, in getitem
raise KeyError(key) from None
KeyError: 'MODULESHOME'

A temporary fix to get jade folder structure was to create a void file '.modulespath' in a dummy folder path (by export MODULESHOME and mkdir init).
