Incorporate effects of irradiation deviating from inverse-square law #667

Feature description

For cases of eccentric orbits, giant stars, small planets, and ultra-short periods, the irradiation environment of a planet deviates from the inverse square law. The IS law assumes that the system is spherically symmetric and the star is a point source. Furthermore, it does not readily incorporate spatial variations across the planet (e.g. near the terminator zone). These effects are especially relevant to USP lava planets.

This recently arose in a separate issue with @maraattia @EmmaPostolec @timlichtenberg: #594.

Going forward, we need a self consistent method for calculating the planetary instellation flux (across the spectrum) based on the orbital, planetary, and stellar parameters.

Preferred solution

There is a package for handling these here: https://github.com/Mradumay137/InstellCa
We could incorporate this Python package within PROTEUS.

Additional information

Lots of binary-star literature on this. See also: https://iopscience.iop.org/article/10.3847/1538-4357/ae29ea
