[ITP] python-scikit-build-core

Hi all,

scikit-build-core (https://pypi.org/project/scikit-build-core/) is a 
dependency of pybind11, which is itself a dependency of recent versions 
of python-imaging (a package I already maintain), and as such I'd like 
to package it for Cygwin.

I haven't yet created a cygport file for this package, but will do shortly.

scikit-build-core is in Debian: 
https://packages.debian.org/trixie/python3-scikit-build-core

This, together with pybind11, will enable me to release the current 
version of python-imaging for Python 3.12 as stable, and start working 
on wxPython for Python 3.12.

Best,
Hamish
