Closure test L1 consistency in random noise generation

Created by: comane

The idea of this PR is that currently (in the master) the MULT uncertainties part of the Covmat used to compute L1 noise in a closure test are computed from the experimental central values (which do not exist within a CT). In this branch the MULT unc. are computed from the L0 central values, i.e., the theory predictions.
