Since returning a valid weather is always considered an updated value,
if the current weather is empty, the face will attempt to display the
temperature and icon as empty values, rather than clearing the labels.
Move the function GetIcon that converts SimpleWeatherService::Icons to char (symbol) into a new header file so that it can be used by other apps and companion apps.
Add missing icons (heavy clouds, thunderstorm, snow).
Remove unneeded comparison operator (!=), improve conversion of Timestamp and MessageType, order includes.
Fix typo in documentation.
Remove not related change in StopWatch.
This new implementation of the weather feature provides a new BLE API and a new weather service.
The API uses a single characteristic that allows companion apps to write the weather conditions (current and forecast for the next 5 days).
The SimpleWeather service exposes those data as std::optional fields.
This new implementation replaces the previous WeahterService.
The API is documented in docs/SimpleWeatherService.md.
Fixes#1467 "Double tapping PineTimeStyle steps style button sends watch to sleep"
Double tap is disabled on the color settings screen by checking if the Rnd button is visible, but this didn't work for the options screen as the Rnd button isn't visible. I've changed it to check if the Close button is visible instead, which is used on both settings screens, and resolves the bug. I also changed the button used to disable the long press behaviour which was an as-yet-undiscovered bug which would have allowed the long press action to be used when the options screen was visible.
value_str is a way to add text on a button without a separate label.
This saves having an extra label object, but uses more memory and is
removed in LVGL8
When the screen switches, the full screen needs to be refreshed for the
hardware scrolling to work. This was enforced with backgroundLabels, but
is simpler to do with a rounder function.
