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.
