abstract: Simplify the loading matrix in factor models using the l1 criterion as proposed
  in Freyaldenhoven (2025) <https://doi.org/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().
