Closes #164
Use the meta package for numpy as a build dep: https://github.com/scipy/oldest-supported-numpy
See:
https://scikit-hep.org/developer/packaging#special-additions-numpy
The reason to use the oldest available Numpy version as a build-time dependency is because of ABI compatibility. Binaries compiled with old Numpy versions are binary compatible with newer Numpy versions, but not vice versa.
