Description: Download climate data for a bounding box, polygon or point
        and return tidy tables. Sources are the 'ERA5' reanalysis
        (Hersbach et al. (2020) <doi:10.1002/qj.3803>) from the
        'Copernicus' Climate Data Store
        <https://cds.climate.copernicus.eu/>, India Meteorological
        Department (IMD) gridded rainfall and temperature (Pai et al.
        (2014) <doi:10.54302/mausam.v65i1.851>), 'HadEX3' climate
        extremes (Dunn et al. (2020) <doi:10.1029/2019JD032263>) and
        'CRU TS' (Harris et al. (2020)
        <doi:10.1038/s41597-020-0453-3>). Computes heat stress indices,
        including wet-bulb globe temperature (Liljegren et al. (2008)
        <doi:10.1080/15459620802310770>) and the Universal Thermal
        Climate Index (Bröde et al. (2012)
        <doi:10.1007/s00484-011-0454-1>), and heatwave indicators,
        including the Excess Heat Factor (Nairn and Fawcett (2015)
        <doi:10.3390/ijerph120100227>).
