    layer: RasterLayer,
    opts?: {
        format?: (v: number) => string;
        tooltip?: {
            destroy: () => void;

        show: (evt: any, html: string) => void;
    };
}
Wire a RasterLayer's hover value to a tooltip. Uses the UNFILTERED map:hover bus event so the tooltip hides the moment the cursor leaves the raster footprint (valueAt → null). Requires fim.enableMapEvents().
Parameters
- layer: RasterLayer
- Optionalopts: {
      format?: (v: number) => string;
      tooltip?: {
          destroy: () => void;
          el: Element;
          hide: () => void;
          show: (evt: any, html: string) => void;
      };
  } = {}
Returns {
    off: () => void;
    tooltip: {
        destroy: () => void;
        el: Element;
        hide: () => void;
        show: (evt: any, html: string) => void;
    };
