Description: Computes rainfall anomaly indices and a standardised
        temperature anomaly from monthly or annual precipitation and
        temperature data supplied by the user. The rainfall indices are
        the Rainfall Anomaly Index (RAI; Van Rooy, 1965), the Modified
        Rainfall Anomaly Index (MRAI) and the Standardized Rainfall
        Anomaly Index (SRAI) of Ekpetere (2025)
        <doi:10.1016/j.jenvman.2025.124160>, the Simplified
        Standardized Precipitation Index (SSPI) of Raziei (2021)
        <doi:10.1016/j.jhydrol.2021.126761>, and the Standardized
        Precipitation Index (SPI; McKee et al., 1993). The temperature
        anomaly is a z-score computed within each calendar month. All
        indices are computed group-wise, so the user can stratify by
        any combination of spatial units (state, district, grid cell)
        and calendar month, and each value can be classified into a
        descriptive severity class.
