Add support for medpro (and medcoupling) on windows

[Krande]

Hey @ldallolio! In connection with conda-forge/staged-recipes#24378 (comment) I used medpro to validate the compiled version of medcoupling on windows. All tests are passing :) (meaning we're close to merging medcoupling and releasing it on conda-forge).

I only had to make a few changes to get it working on windows.

• I made a pytest fixture for the example dir and used pathlib to ensure it would resolve the relative path more easily.
• And I had to add a conditional so that it uses a different write method on windows.

Let me know if you have any comments?

Best Regards
Kristoffer

Hi Kristoffer,

You did I great job ! I will make this into a conda-forge package as soon as we get medcoupling accepted :)
You used the "write" method instead of the "write33" in windows, I supposed it worked better in your case, it will write in the new med 4 format instead of the "old" 3.3.1 format (not a big deal for a lot of people), did you have some issues with write33 ?

Thank you for your contribution!
All the best,
Luca

Yeah, write33 resulted in InterpKernelException:

medcoupling.InterpKernelException: Return code of MEDFile call "MEDfileCommentWr" is not 0 as expected during writing operation ! ( Return code was -1 at C:\work\miniforge3\envs\mamba-build\conda-bld\medcoupling_1710416826555\work\src\MEDLoader\MEDFileData.cxx:369 ). Check write access on MED file ?

Aha, so that's the difference between the different write methods. Good to know!
