TODO:

• [ ] Strange artifacts on background image
• [ ] Either remove location or find API to get Location from long,lat as GPS data only gets us long, lat.
• [ ] Periodically fetch weather in background to avoid delay when opening Weather App
• [ ] Use this weather for watchface weather instead of unreliable weather through Gadgetbridge and external app
