enh: add py-hepstats package

[jonas-eschle]

add the hepstats package. Requires #43695

[tldahlgren]

Looks like this package needs a bit of work.

[tldahlgren]

Can't confirm sha256 or stage the package.

While I think the pypi works now (?) after going back and forth, I've encountered the following error when building:

==> py-hepstats: Executing phase: 'install'
==> Error: AttributeError: 'super' object has no attribute 'install'

The 'py-hepstats' package cannot find an attribute while trying to build from sources. This might be due to a change in Spack's package format to support multiple build-systems for a single package. You can fix this by updating the build recipe, and you can also report the issue as a bug. More information at https://spack.readthedocs.io/en/latest/packaging_guide.html#installation-procedure

/workdir/spack/lib/spack/spack/builder.py:147, in __getattr__:
        146        def __getattr__(self, item):
  >>    147            result = getattr(super(type(self.root_builder), self.root_builder), item)
        148            if item in super(type(self.root_builder), self.root_builder).phases:
        149                result = _PhaseAdapter(self.root_builder, result)
        150            return result

I cannot make any sense of it, @tldahlgren , any ideas?

I am unable to reproduce the problem (because I'm getting a number of packages that are having problems with finding python.h).

Perusing the sources, I don't see how this can be happening for that package and I'm not seeing any commits since your update that stand out as having this effect.

Please submit an issue with the requested information.

A clean install... magically made it work. I can confirm now that it builds (the extra, which is off by default, requires zfit, PR here: #43695, that's why the CI is failing)
