Fix: uncertainty computations #171

Closed GilesStrong closed 1 year ago

Simplifies uncertainty computations for scattering variables and volume predictions. Was sig_isig_jdvar/didvar/dj for all inclusive combinations of hits i,j. Now (sig_idvar/di)^2 Previous version attempted to account for correlated uncertainties, but didn't implement them correctly.

I think that for the volume predictions, the uncertainties will be correlated, but the calculation takes so long to run, that it is not practical to actually use it. For the scattering inference, the uncertainties are hit-based, so no correlations are expected.
