SimpleWeather service : new weather implementation

Browse source 
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.

# Simple Weather Service
## Introduction
The Simple Weather Service provide a simple and straightforward API to specify the current weather and the forecast for the next 5 days. It effectively replaces the original Weather Service (from InfiniTime 1.8) since InfiniTime 1.14
## Service
The service UUID is `00050000-78fc-48fe-8e23-433b3a1942d0`.
## Characteristics
## Weather data (UUID 00050001-78fc-48fe-8e23-433b3a1942d0)
The host uses this characteristic to update the current weather information and the forecast for the next 5 days.
This characteristics accepts a byte array with the following 2-Bytes header:
- [0] Message Type :
- `0` : Current weather
- `1` : Forecast
- [1] Message Version : Version `0` is currently supported. Other versions might be added in future releases
### Current Weather
The byte array must contain the following data:
- [0] : Message type = `0`
- [1] : Message version = `0`
- [2][3][4][5][6][7][8][9] : Timestamp (64 bits UNIX timestamp, number of nanoseconds elapsed since 1 JAN 1970)
- [10] : Current temperature (°C)
- [11] : Minimum temperature (°C)
- [12] : Maximum temperature (°C)
- [13]..[44] : location (string, unused characters should be set to `0`)
- [45] : icon ID
- 0 = Sun, clear sky
- 1 = Few clouds
- 2 = Clouds
- 3 = Heavy clouds
- 4 = Clouds & rain
- 5 = Rain
- 6 = Thunderstorm
- 7 = snow
- 8 = mist, smog
### Forecast
The byte array must contain the following data:
- [0] : Message type = `0`
- [0] : Message version = `0`
- [2][3][4][5][6][7][8][9] : Timestamp (64 bits UNIX timestamp, number of nanoseconds elapsed since 1 JAN 1970)
- [10] Number of days (Max 5, fields for unused days should be set to `0`)
- [11] Day 0 Minimum temperature
- [12] Day 0 Maximum temperature
- [13] Day 0 Icon ID
- [14] Day 1 Minimum temperature
- [15] Day 1 Maximum temperature
- [16] Day 1 Icon ID
- [17] Day 2 Minimum temperature
- [18] Day 2 Maximum temperature
- [19] Day 2 Icon ID
- [20] Day 3 Minimum temperature
- [21] Day 3 Maximum temperature
- [22] Day 3 Icon ID
- [23] Day 4 Minimum temperature
- [24] Day 4 Maximum temperature
- [25] Day 4 Incon ID

/**
* Different weather events, weather data structures used by {@link WeatherService.h}
*
* How to upload events to the timeline?
*
* All timeline write payloads are simply CBOR-encoded payloads of the structs described below.
*
* All payloads have a mandatory header part and the dynamic part that
* depends on the event type specified in the header. If you don't,
* you'll get an error returned. Data is relatively well-validated,
* so keep in the bounds of the data types given.
*
* Write all struct members (CamelCase keys) into a single finite-sized map, and write it to the characteristic.
* Mind the MTU.
*
* How to debug?
*
* There's a Screen that you can compile into your firmware that shows currently valid events.
* You can adapt that to display something else. That part right now is very much work in progress
* because the exact requirements are not yet known.
*
*
* Implemented based on and other material:
* https://en.wikipedia.org/wiki/METAR
* https://www.weather.gov/jetstream/obscurationtypes
* http://www.faraim.org/aim/aim-4-03-14-493.html

* mg/m³ CO2, CO
