Description: Implements Goldberg's (2006) <doi:10.1016/j.jrp.2006.01.001>
    bass-ackwards method and modern descendants for hierarchical structural
    analysis. Extracts solutions from 1 to k factors using principal
    component analysis (PCA), exploratory factor analysis (EFA), or
    exploratory structural equation modeling (ESEM) engines, then
    characterizes the hierarchy via between-level factor-score
    correlations computed via exact linear algebra (Waller, 2007,
    <doi:10.1016/j.jrp.2006.08.005>) or materialized scores. Includes the
    Forbes (2023) <doi:10.1037/met0000546> extension for redundancy pruning
    and all-levels cross-correlations.
