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. A complementary family clusters variables by their
        regression response to covariates rather than by their
        covariance, sharing one profile per cluster. See Tous & Chiquet
        (2026) <doi:10.1016/j.csda.2026.108347> for the model itself
        and its variational expectation-maximization estimation
        procedure.
