Bug Description

The data property that can be passed to the annotations is not added to the properties in geojson.

I know it can be done by setting the annotationColor properties from the specific annotation options but that would create such a messy function with a lot of nested if elses or switch cases that I rather just add in custom properties with a customised layer so that the map styles handle it

Other then that I think it will also benefit that the general onFeatureTapped also gets all the data properties that are in that feature.

Steps to Reproduce

1. Create custom annotation layer style with data driven element
2. Create annotation with data property set to anything
3. add annotation to map

Expected Results

Data properties to be added to the geojson properties so that they can be used in layer styles.

Actual Results

data is not used or passed to the togeojson

Code Sample

class EventLayerManager extends AnnotationManager {
  EventLayerManager(super.controller) : super(enableInteraction: false);

  void addEvent(final LatLng geometry, final String type) async {
    final options = CircleOptions(geometry: geometry);

    final circle = Circle('some_id', options, {'type': type});

    await add(circle);
  }

  @override
  List<LayerProperties> get allLayerProperties => [
        CircleLayerProperties(
          circleRadius: 2,
          circleColor: [
            'match',
            ['get', 'type'],
            'accident', 'red',
            'blue',
          ],
        ),
      ];
}
