Add a new ClimateDataController in API v1 namespace at /api/v1/climate as base URL, with the following methods:

@GetMapping("/current/{latitude},{longitude}")
public TileClimate getCurrentClimate(@PathVariable("latitude") double latitude, double longitude) {
  Long tileIndex = WorldClimUtil.getWorldclim25Tile(longitude, latitude);
  if (tileIndex == null) {
    throw new NotFoundElement("No current climate data for specified (lat, lon)");
  }
  return climateDataService.climateForTile(tileIndex);
}

@GetMapping("/past/{latitude},{longitude}")
public TileClimate getPastClimate(@PathVariable("latitude") double latitude, double longitude) {
  throw new NotFoundElement("Past climate data not available");
}


@GetMapping("/future/{latitude},{longitude}")
public TileClimate getPastClimate(@PathVariable("latitude") double latitude, double longitude) {
  throw new NotFoundElement("Future climate data not available");
}
