+ * 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
