SimpleWeather service : new weather implementation

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.
