[SciPy-Dev] Making it easier to pin numpy in pyproject.toml

[Prabhu Ramachandran]

Hi Thomas,

Thanks for doing this, I think this would be very useful for multiple projects
that use numpy as a build dependency.  I agree with Ralf that it would perhaps
make more sense to have a pyproject.toml with the correct requirements in the
oldest-supported-numpy project in addition to or in place of the setup.cfg you
have.

Regards,
Prabhu
