feat: get climate data from ERA5

Climate information:

• Annual precipitation
• Annual potential evapotranspiration

For this application, we used the online source https://app.climateengine.org/climateEngine; however, others also seem promising, such as https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels?tab=overview.
