That looks right--of course, for bleeding edge versions of Python or on some platforms that were only recently supported like ARM and Mac M1, we probably need even newer NumPy, but I suspect that can eventually be encoded in the pyproject.toml stuff.

[tylerjereddy]

I'll just put this in instead of suggesting that we use a variable to maintain that version in a single place (vs. error message, setup reqs and install reqs locations), since writing more shim code in setup.py probably isn't the best solution long-term anyway.

Thanks!
