Support numpy >= 1.22

**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!
