Description
We should consider adding an implementation of the GTI DIRINT model described in Marion 2015:

In short, the GTI DIRINT model converts plane of array irradiance to DNI, DHI, and GHI.
I have a partial implementation that I've been sitting on for a few months. I'll try to get it into a PR soon.
