Description: Calculates and visualises speech rhythm and timing metrics. The
    'rhythm.metrics' package provides a standardised workflow to compute
    common metrics including Delta C, Delta V, VarcoC, VarcoV, the
    percentage of vocalic intervals (%V), and both raw and normalised
    Pairwise Variability Indices (rPVI, nPVI). It includes functions for
    calculating and visualising these measures to facilitate cross-linguistic
    and developmental rhythm research. Delta C, Delta V, and %V measures are
    based on Ramus et al. (1999)
    <doi:10.1016/S0010-0277(99)00058-X>; VarcoC and VarcoV measures are
    based on Dellwo (2006, ISBN: 9783631554777); and rPVI-C and nPVI-V are
    based on Grabe & Low (2002) <doi:10.1515/9783110197105.2.515>.
