Description: Implements 'glmnet'-style complex-valued lasso (CLASSO)
        and complex-valued graphical lasso (CGLASSO) via a pathwise
        coordinate descent algorithm for complex-valued parameters,
        using an isomorphism between complex numbers and 2x2 orthogonal
        matrices. Also provides a full inference pipeline for
        high-dimensional sparse spectral precision matrices, including
        data-driven bandwidth selection, one-step debiasing, asymptotic
        variance estimation, entry-wise confidence regions, and
        FDR-controlled hypothesis testing. Supporting tools for
        cross-validation, simulation, coefficient extraction, and
        plotting are included. See Deb, Kuceyeski, and Basu (2024)
