Description: Implements the moment-matching approximation for differences
    of non-standardized t-distributed random variables in both univariate and 
    multivariate settings. The package provides density, distribution function,
    quantile function, and random generation for the approximated distributions
    of t-differences. The methodology establishes the univariate approximated
    distributions through the systematic matching of the first, second, and
    fourth moments, and extends it to multivariate cases, considering both
    scenarios of independent components and the more general multivariate
    t-distributions with arbitrary dependence structures. Methods build
    on the classical moment-matching approximation method (e.g., Casella and
    Berger (2024) <doi:10.1201/9781003456285>).
