Description: Implements the Normal-Block model, a Gaussian graphical model
             with a latent clustering structure for the multivariate analysis
             of continuous data. The model clusters variables and, building
             on the graphical lasso, infers a network of statistical
             dependencies between clusters rather than between individual
             variables, for known or unknown clusterings, with an optional
             zero-inflation extension for data with an excess of exact
             zeros. See Tous & Chiquet (2026)
             <doi:10.1016/j.csda.2026.108347> for the model itself and its
             variational expectation-maximization estimation procedure.
