Fix build on Windows

[rmarquis]

Using the build frontend, we realized the build/packaging was not succeeding correctly, resulting in the dimlp and fidex libraries missing from the binary wheel.

After investigation, it seems the hatch build backend is not approriate for binaries with bindings. An alternative way is to use the scikit-build-core build backend, which is simple and works great with one caveat: it requires the WIndows binaries to be built with MSVC as MingW is not supported (which makes sense as Python windows banaried are built with msvc).

In turn, this requires the CMake files to be adjusted for MSVC. Some partial work is available in the fixbuildmsvc branch. Some minor code changes might be required too.

Alternative:

• Go back to poetry backend, with all of the issues that this implies (see Migrate to PEP-621 compliant pyproject.toml #94 and the various performance and dependencies issues).
