Description: Implements the sparse-group lasso method of Zhang et al.
        (2020) <doi:10.1007/s10107-018-1329-6>. Unlike many widely
        available methods based on first-order descent, this method
        uses second-order information to solve the dual optimization
        problem via a semismooth Newton method.
