Description: Implements an algorithm for computing multiple sparse principal 
    components of a dataset. The method is based on Cory-Wright and Pauphilet 
    "Sparse PCA with Multiple Components" (2026) 
    <doi:10.1287/opre.2023.0598>. The algorithm uses an iterative deflation 
    heuristic with a truncated power method applied at each iteration to compute 
    sparse principal components with controlled sparsity.
