Description: Efficient implementation of sparse group lasso with
        optional bound constraints on the coefficients; see Liang, et
        al., (2024) <doi:10.18637/jss.v110.i06>.  It supports the use
        of a sparse design matrix as well as returning coefficient
        estimates in a sparse matrix. Furthermore, it correctly
        calculates the degrees of freedom to allow for information
        criteria rather than cross-validation with very large data.
        Finally, the interface to compiled code avoids unnecessary
        copies and allows for the use of long integers.
