feature
Add a Feature to the GeojsonSource. Data will be parsed from collection to String in a worker thread and use main thread to pass this data to gl-native.
In order to capture events when actual data is drawn on the map please refer to Observer API and listen to MapEvents.SOURCE_DATA_LOADED (optionally pass data-id to filter the events) or MapEvents.MAP_LOADING_ERROR with type = metadata if data parsing error has occurred.
Note: This method is not thread-safe. The Feature is parsed on a worker thread, please make sure the Feature is immutable as well as all collections that are used to build it.
Parameters

the feature
data
optional metadata to filter the SOURCE_DATA_LOADED events later
