AcMapLayerProviderComponent options input only accept url

[bentfc]

In the last version of code, the class "AcMapLayerProviderComponent":

@Component({
  selector: 'ac-map-layer-provider',
  template: '',
})
export class AcMapLayerProviderComponent implements OnInit, OnChanges, OnDestroy {

  /**
   * refer to cesium docs for details https://cesiumjs.org/Cesium/Build/Documentation/ImageryProvider.html
   */
  @Input()
  options: { url?: string } = {};

  ...

should become something like that:

@Component({
  selector: 'ac-map-layer-provider',
  template: '',
})
export class AcMapLayerProviderComponent implements OnInit, OnChanges, OnDestroy {

  /**
   * refer to cesium docs for details https://cesiumjs.org/Cesium/Build/Documentation/ImageryProvider.html
   */
  @Input()
  options: { url?: string, [key:string]: any } = {};

  ...

Declaring options like that allows to add whatever field needed for the chosen provider. Most of them are using much more than just a url.

To more exhaustive, all provider has its own options definition that are declared in cesium.d.ts file. So the input must be one of those type.

/**
   * refer to cesium docs for details https://cesiumjs.org/Cesium/Build/Documentation/ImageryProvider.html
   */
  @Input()
  options: Cesium.WebMapServiceImageryProvider.ConstructorOptions | Cesium.WebMapTileServiceImageryProvider.ConstructorOptions | Cesium.ArcGisMapServerImageryProvider.ConstructorOptions |
    Cesium.SingleTileImageryProvider.ConstructorOptions | Cesium.BingMapsImageryProvider.ConstructorOptions | Cesium.GoogleEarthEnterpriseMapsProvider.ConstructorOptions | Cesium.MapboxImageryProvider.ConstructorOptions |
    Cesium.MapboxStyleImageryProvider.ConstructorOptions | Cesium.UrlTemplateImageryProvider.ConstructorOptions | Cesium.OpenStreetMapImageryProvider.ConstructorOptions;

Also, url field isn't mandatory as declared on the previous post but the following code check and raise an error if the url isn't declared and the provider isn't OFFLINE.

...

ngOnInit() {
    if (!Checker.present(this.options.url) && this.provider !== MapLayerProviderOptions.OFFLINE) {
      throw new Error('options must have a url');
    }

...

This check should not exist anymore as for exemple 'MapboxStyleImageryProvider' doesn't need any url if styleId, accessToken and username are declared.
