Support numpy >= 1.22

[jaytmiller]

Is your feature request related to a problem? Please describe.
Having a build constraint of numpy<1.22 is constraining on other packages installed in the same environment. numpy is now at 1.25.x.

Describe the solution you'd like
Try out newer versions of numpy to determine if the <1.22 constraint is still needed. If not, make changes to keep up with numpy evolution. If it's straightforward for non-experts to help out, let me know.

Describe alternatives you've considered
None, other than dropping exoplanet from our TIKE environment.

Additional context
Don't get me wrong, we want exoplanet and salute the hard work!

Unfortunately this is non-trivial because the issue is with Theano, which is an (abandoned!) dependency of PyMC3. You might recommend supporting more recent versions of PyMC that don't depend on Theano, but unfortunately that's a bigger project and there are various reasons beyond the scope of this conversation that make me hesitant.

It's possible that we could hack something to get this at least working. I'll take a peek, but definitely no promises!

Great, thanks for your insight! (That's already quite a bit of unwinding about where the real problem is, very helpful.)
