Closes #3314

Overview

  • Updated uncertainty values in geometric factor csvs (v4) to be 1/1000th of previous values (which were in [eV]).
  • calculate_intensities and calculate_backgrounds now propagate the asymmetric GF uncertainty with the exact reciprocal relation (J·G/(G ∓ dG), emit _sys_err_plus / _sys_err_minus bounds, and store the geometric mean sqrt(minus·plus) in the existing _sys_err variable. Applied to ena_intensity, bg_rate, and bg_intensity.
  • Made changes to tests to match the correct formulas.
