feat: add weather map and wind tools

Add get_weather_map, which returns the latest NOAA radar, satellite or
lightning map over an area as an image, choosing a window the image
route accepts and reporting areas outside the product's coverage, and
get_wind, which samples GFS or IFS wind at a location with the wind
layer's own grid sampling.
