fire weather

Calculates the Canadian Fire Weather Index components from an hourly forecast: the Fine Fuel Moisture Code for the surface litter that carries ignition, the Duff Moisture Code and Drought Code for the deeper layers that determine whether a fire keeps going, the Initial Spread Index combining wind with surface dryness, the Buildup Index, and the resulting Fire Weather Index. Each is returned separately rather than only as a final number, because they answer different questions: a high FFMC.
