Alrighty, this is ready for review. The main change here is that while building the conda package now we will use the packages from conda and while building the wheel we stick to conan to fetch the deps. I also made some changes to the cpp code to make compilers on mac and windows happy. The windows one was complaining about using reserverd keywords like and, or, not. I also made some cosmetic changes to get rid of some warnings and I can remove them from this PR if we don't want to mix those things up with this change.

Another thing that could be controversial is that I am using different tbb versions for conda and pypi. conda has the latest tbb=2022.0.0 but conan does not have the new releases yet. I can sync them up if required.

The last commit has the action build logs for wheels and conda https://github.com/scipp/scipp/actions/runs/12706404682/job/35419301931

We should check if this works with Mantid. In the past we had to stick with some older version because Mantid uses it as well.

Hmm, need to find a machine to run the test. I guess running this https://scipp.github.io/scippneutron/user-guide/from-mantid-to-scipp.html should be enough right?

Yes. Why can't you use your own machine? The TBB version bump happened across platforms, didn't it?

mantid on conda doesn't work with Mac ARM?

I was able to go through https://scipp.github.io/scippneutron/user-guide/from-mantid-to-scipp.html on a linux machine just fine. I just checked to see if there were any errors pop up in cells. Didn't see anything pop up.
