oops thank you for the spelling fix...

I agree with this choice
I think it's maybe worth editing those down the line but no need to change it here. 👍 |

This PR originally started much larger---actually changing all calls from
AbsorptionCoefficienttoSpecificAbsorptionOpacity. After some retrospection, a simple change of mindset got me on board with instead dealing with absorption coefficients. I'd like to discuss this via meeting.After this realization, this PR shrunk to only changing out some calls to
AbsorptionCoefficientto directly returning rho * kappa (where rho is the material density and kappa is the material specific absorption opacity), instead of arriving there via Kirchhoff's laws.I kept the functions for
*FromKirchhoffin this PR for photons, even though they are not used, as I think they do help guide readers of the code as to what things correspond to. Neutrinos also have calls to*FromKirchhoff(e.g., for the tophat absorption coefficient), but I did not edit these (was this the right move?).
