Description: Simplify the loading matrix in factor models using the l1
        criterion as proposed in Freyaldenhoven (2025)
        <doi:10.21799/frbp.wp.2020.25>. Given a data matrix, find the
        rotation of the loading matrix with the smallest l1-norm and/or
        test for the presence of local factors with main function
        local_factors().
