add support for triangular matrices to MultivariateNormalDistribution and simplify loading of FFs #247

Closed peterstangl closed 10 months ago

peterstangl commented 10 months ago

This PR adds support for triangular covariance and correlations matrices to the MultivariateNormalDistribution class, filling missing values by reflecting the upper triangle at the diagonal. Similar constructions in the functions loading the form factor parameters are removed and these functions are simplified.
