Sunrise & Sunset time

[vkareh]

I have a prototype branch for both InfiniTime and Gadgetbridge where a new version of the SimpleWeatherService has space allocated for sunrise and sunset times. This allows both the weather app and the watchfaces to display different icons depending on whether it's daytime or nighttime.

Some screenshots:

This is just an example of what can be done with this data. However, a more important thing I'm looking into is having a night mode on the watch, where the screen can optionally go to a dimmer setting and the watchface can change colour to more red-ish tones.

Any other ideas of what can be done with this data?
