Function mouseEnterOnLayer

mouseEnterOnLayer(listenerId, layerId, fn): void
JMap.Event.Map.on.mouseEnterOnLayer

This event is triggered when the mouse enter over a layer feature on a specific layer.

When switching from one feature to another, this event is not called again if the features are joined or intersect. This event only works on vector layers

IMPORTANT! : This event currently only works when a JMap layer's "base style" is displayed on the map (non-thematic), and only works well with a base Style Rule with only one condition and one Style Map Scale on JMap Cloud
Parameters
- listenerId: string
  Your listener id (must be unique for all map events)
- layerId: JId
  The JMap Layer Id
- fn: ((params) => void)
  Your listener function
  - - (params): void
    - Parameters
      params: JMapEventFeaturesParams
      Returns void

Example
```
// When mouse is entering over layer id=2 feature(s), will display 2 messages
// in the console
JMap.Event.Map.on.mouseEnterOnLayer(
   "custom-map-mouse-enter",
   2,
   args => {
     console.log(
         `The mouse entered an element of layer id="${args.layerId}"`,
         args.map, args.mapEvent // mapEvent is the Maplibre event
     )
     console.log(
       `The mouse cursor is over ${args.features.length} features`,
       args.location
     )
   }
)
