Pollen forecasting powered by FMI SILAM and EAN.

Latlon coordinates are stored by the code in this project in the order (lon, lat). Coordinates are formatted and displayed to users in the order (lat, lon). Some external crates/functions use the order (lat, lon) and this is indicated in this project's code where relevant.

• Periodically fetch data - probably ~02.00 UTC each day fetch latest model run
• Pretty webpage - make it look nice
• Reverse geocoding - displays name of location based on coordinates
• Geocoding - enter address/city/whatever and it gets coordinates
• Caching - set Cache-Control max-age to be the next time data will be fetched
• Rate limit geocoding - max 1 request per second to Nominatim
• Alternate geocoders - add other providers as fallback for when Nominatim is busy
