Description: Computes and compares multiple measures of separation and overlap
    between phonological categories (for example vowels or consonants) in
    arbitrary multi-dimensional acoustic spaces such as formant values,
    mel-frequency cepstral coefficients (MFCCs), duration, or learned
    embeddings. The main entry point, phontrast(), reports several contrast
    metrics in one call -- Jensen-Shannon divergence and distance (Lin, 1991)
    <doi:10.1109/18.61115>, the Pillai-Bartlett trace, Bhattacharyya distance
    and affinity, Mahalanobis distance, and proportional overlap -- globally or
    by group on a common separation-oriented scale, with bootstrap confidence
    intervals. Also provides utilities for preparing estimates for downstream
    modelling such as generalized additive models and mixed-effects models.
    Formerly released as 'phonJSD'.
