Description: Implements omnibus tests for comparing two right-censored survival
    samples that are powerful against sparse departures from equal hazards,
    where the hazard difference is concentrated in a small and a priori unknown
    subset of the follow-up. Exact hypergeometric p-values are computed for each
    time interval and aggregated with the Higher Criticism statistic of Donoho
    and Jin (2004) <doi:10.1214/009053604000000265>, or alternatively with the
    Berk-Jones, Fisher or minimum-p statistics. Global p-values are obtained by
    permuting group labels, and the intervals driving a detection can be
    recovered for diagnostic plotting. Tests accept either two samples as
    vectors or the usual survival formula. The method is described in Kipnis,
    Galili and Yakhini (2026) <doi:10.1093/biomet/asaf075>, and the companion
    application note is Kipnis, Galili and Yakhini (2026)
    <doi:10.48550/arXiv.2610.07268>.
