Update Numpy and Cython for Python 3.10 and 3.11 builds

[OCopping]

This PR sets the wheel builds for Python 3.10 and 3.11 to use Numpy 2.0.1

[mdavidsaver]

With reference to the discussion starting here #145 (comment)

I think some changes and additions will be necessary.

1. In setup.py, conditional computing of install_requires to use the existing "assume ABI forward compatibility ..." computed range when building against numpy 1.x, and numpy >= 1.7 when building against 2.x.
2. In src/p4p.h, define NPY_NO_DEPRECATED_API unconditionally, and add a definition of NPY_TARGET_VERSION to 1.7.
3. In pyproject.toml, I think the numpy dependency would simply be numpy >= 1.7. The specific versions in .github/workflows/build.yml should take precedence for pypi.org builds, and would let users continue to build from source against numpy 1.x .

This would clearly state that numpy 1.7 is the minimum support by P4P.

eg. when building against numpy 1.10.0, the install_requires would end up as: ["numpy >= 1.10.0", "numpy < 2"].

eg. when building against numpy 2.0.0, the install_requires would end up as: ["numpy >= 1.7", "numpy < 3"].

As mentioned at the bottom at some point it would be good to test the backwards compatibility at the end of a 2.x build by rolling back numpy and re-running the unit tests. I don't see this as a blocker for this PR.

It seems that removing the condition for this breaks the builds...
#if CYTHON_HEX_VERSION>=0x03000000

[OCopping]

Also NumpyVersion was only added to numpy in version 1.9, so we would either have to try/except around the call, or set the floor to 1.9 if we were to stick with the approach

Replacing NPY_CARRAY_RO with NPY_ARRAY_CARRAY_RO resolves this for me.

Also NumpyVersion was only added to numpy in version 1.9, ...

A negative hasattr() test for NumpyVersion seems like a solid < 2.0 indicator.

Even with these changes, I am still seeing a couple of build failures.

One appears to be a bug in numpy 2.0.1 building with MSVC. fatal error C1021: invalid preprocessor command 'warning' in numpyconfig.h. This is legit as # warning ... is a GNU extension. Interesting that their CI didn't catch this...

The Linux py3.9 manylinux2010_x86_64 job does not find a numpy 2.0.1. Indeed there is no manylinux wheel for 3.9

ERROR: Could not find a version that satisfies the requirement numpy==2.0.1 (from versions: 1.19.3, 1.19.4, 1.19.5, 1.20.0, 1.20.1, 1.20.2, 1.20.3, 1.21.0, 1.21.1, 1.21.2, 1.21.3, 1.21.4, 1.21.5, 1.21.6)

The OSX 3.7 build fails with what I hope is a caching glitch.

[OCopping]

The Linux py3.9 manylinux2010_x86_64 job does not find a numpy 2.0.1.

I have a fork with a branch looking at updating supported versions and images (including arguing for the removal of Python 2.7 and 3.5 support), and using manylinux_2_28_x86_64 has Numpy 2.0 for Python 3.9

@mdavidsaver are you happy to merge this PR in so we can make another beta release to allow people to test their builds with Python 3.10 and 3.11? We can then merge in the Numpy fix for Windows builds in another PR?

[mdavidsaver]

I made another iteration to pin the windows builds to numpy 1.x until the #warning issue can be addressed. Well, all but the py3.12 windows job. Apparently that #warning was added earlier than I expected, effecting all numpy wheels uploaded for py3.12. So I think that specific combination will have to wait for a fix to numpy.

[AlexanderWells-diamond]

@mdavidsaver Just to confirm, do you want to wait for a Numpy release that fixes that particular issue, or are you happy if we try and work around it?

[mdavidsaver]

At this point the numpy fix for MSVC is merged, but not released. I have re-triggered all jobs to see if they still pass. If so, then I think I am ok with disabling/ignoring the one failing job until the next numpy release.
