Description: Five distinct methods are implemented for evaluating the
        sums of arbitrary negative binomial distributions. These
        methods are: Furman's exact series representation (Furman
        (2007) <doi:10.1016/j.spl.2006.06.007>), an FFT-based approach,
        a "hybrid" approach that uses FFT for non-extreme probabilities
        and falls back to the series representation for extremely low
        probabilities, saddlepoint approximation, and a
        method-of-moments approximation. Functions are provided to
        calculate probability masses, cumulative probabilities, and
        quantiles of the convolutions in question using said evaluation
        methods. Functions for generating random deviates from negative
        binomial convolutions and for directly calculating the mean,
        variance, skewness, and excess kurtosis from cumulants are also
        provided.
