CCL >= 3.1.2 doesn't play nice with pytest

[James11222]

In release 3.1.2, @henryiii and I helped fix a bug that enables pyccl to be pip installable again. The fix we added to make the package pip installable was to add numpy as a build requirement for the package, but ultimately we find that this causes issues when working with pytest. In particular, I find that the pytest package doesn't play nice with versions of pyccl>=3.1.2 (below I post the segmentation fault error @henryiii and I found when running pytest on a test file that only contains import pyccl, it will throw this error.).

I think the only way to fix this issue would be to ship distribution wheels in the pip installation so we don't have to build pyccl natively (as suggested in #1219 (comment)).
