Fix compilation for python 10 and numpy 2.2.6

[MarilynKeller]

This merge request fixes a compilation error that occurred when building with:

NumPy 2.2.6
Python 3.10.0

The issue was due to incorrect type casting when passing PyObject* to PyArray_DATA and PyArray_DIMS, which now expects a const PyArrayObject* as of recent NumPy versions.

Changes

Explicit cast added in mesh/src/*.cpp

PyArray_DATA(py_v) -> PyArray_DATA((PyArrayObject*)py_v)
PyArray_DIMS(py_v) -> PyArray_DATA((PyArrayObject*)py_v)

Makefile updated:

l.7 -- 	--install-option  -> --config-settings 

As --install-option is not supported by modern pip
