Description: Fits topic models using varimax-rotated principal component
    analysis (PCA), following the "vintage factor analysis" approach of
    Rohe & Zheng (2020) <doi:10.48550/arXiv.2004.05387>. Leverages truncated PCA via 'irlba'
    for sparse matrices, enabling fast model fitting on large corpora.
    Includes an information-theoretic approach to vocabulary selection,
    'broom'-compatible tidiers for extracting word-topic and topic-document
    matrices into a tidy data workflow, and samplers for constructing
    simulated corpora for benchmarking and method evaluation.
