Test workflow failing due to issues building `so3` test dependency
Our tests workflow is currently failing on Ubuntu / Python 3.8 - see for example this run log. This is due to errors when building so3 a test dependency using Cython. While this is happening specifically on Ubuntu / Python 3.8 in our test matrix, but from some local testing I think it may also affect other Python versions but the workflows on GitHub Actions are using cached wheels from a previously successful build.
