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.
