Description: Improves the interpretation of the Standardized
        Precipitation Index under changing climate conditions. The
        package uses the nonstationary approach proposed in Blain et
        al. (2022) <doi:10.1002/joc.7550> to detect trends in rainfall
        quantities and to quantify the effect of such trends on the
        probability of a drought event occurring.
