/**
 * IconLayerSource is a React component that creates and manages a DeckGL IconLayer.
 * This component uses the `IconLayer` from `@deck.gl/layers` to render icon markers
 * based on GeoJSON or array data, with support for selection coloring and interactivity.
 * It also integrates tooltip functionality for hover, click, and selection-based tooltips.
 *
 * **Note:** The `layerStyle` object must include both `iconAtlas` (the icon sprite image)
 * and `iconMapping` (an object mapping icon names to their positions/sizes in the atlas).
 * If either is missing, the IconLayer will not render.
 *
 * **Note:** Added default `getPosition` accessor to ensure proper icon placement and getSize
 * for icon sizing. Otherwise there might be issues with icons not appearing.
 * These can be overridden by providing them in the `layerStyle`.
 *
 * @param {LayerSourceProps} props - The props for the IconLayerSource component.
 * @param {RenderingLayer} props.layer - The layer configuration object.
 * @param {(id: string, instance: IconLayer | null) => void} props.onLayerUpdate - Callback to handle updates to the layer instance.
 * @returns {React.ReactNode} Tooltip element for this layer (if any), no DOM for the layer itself.
