Fix compatibility with numpy2

[avalentino]

This is a minimalistic patch to fix compatibility with numpy2.
It only partially supersedes #183, changes to teh CI configuration and setup.py/pyproject.toml are not included.

Looks like CI changes might be needed. Is there any way you could apply your changes on top of that PR (especially if you can do it with the original commits)? Then I can try to get the CI working again.

Changes in affafa1 are not sufficient I fear.
I will try to fix ci.yaml by the way.

I don't think my configuration is wrong, but the CI just can't seem to download conda packages consistently right now.

I think I've fixed the main problem with the system-provided libtiff which was a missing .py copy of the header. I generated it locally with docker and committed it. I've also updated the CI conda installation to not use defaults at all. Due to licensing issues no one should use the defaults conda channel unless they are paying money to Anaconda. We aren't, so we won't use it.

My guess on the mac failures is:

#178

and the almost fix:

#179

Thanks @djhoese
For the record I think that also tiff_h_4_7_0.py is missing.
LibTIFF v4.7 seems to be the one used in the failed job on Mac.
Not sure if it makes any real difference.

[djhoese]

Added it but mac still failing. I really don't understand what is going on with conda downloads in CI today. A ton of them fail and restarting sometimes fixes it.
