BLD: Build against numpy >= 2.0.0rc1

This unpins numpy<2 and builds the SWIG C library against numpy >=
2.0.0rc1. Versions of numpy major 2 are backward compatible with numpy
1. Hence we should not see issues in environment where numpy<2 may be
maintained for years to come, i.e. RMS environments.

The numpy SWIG bindings committed in this repository are not out-of-date
in a way that would break compatibility. The last update to them in
numpy's repository was two years ago from the time of this commit.
