ICS_lcov

It is a wrapper for the local shape estimator of scatter
as computed by <code>fpc::localshape()</code>.

Implementation of tandem clustering with invariant coordinate
selection with different scatter matrices and several choices for the
selection of components as described in Alfons, A., Archimbaud, A., Nordhausen, K.and Ruiz-Gazen, A. (2024) <doi:10.1016/j.ecosta.2024.03.002>.
