STYLE_LOADED

The requested style has been fully loaded, including the style, specified sprite and sources' metadata. ``` text Event data format (Object). ``` Note: The style specified sprite would be marked as loaded even with sprite loading error (An error will be emitted via `MapLoadingError`). Sprite loading error is not fatal and we don't want it to block the map rendering, thus this event will still be emitted if style and sources are fully loaded.
