Generates a tiny 64x32 image of today's weather forecast as a PNG file, for use on a pixel display. Uses the openweathermap API and the jimp library.
You'll need to create a config.json file with latitude, longitude and apiKey properties. The apiKey must be an api key registered with openweathermap.
When you run the application weather.png is updated in the same folder, unless you pass --filename.
You can pass --days=n to produce a png for n days in the future.
