src/ol-ext: fix validation GeoJSON GeometryCollection geometry coordinates type

[tmszi]

Describe the bug
The <vl-interaction-select> component incorrectly validate feature property if it is GeoJSON GeometryCollection geometry type.

vuelayers/src/components/select-interaction/interaction.vue

Line 84 in 6dc131f

validator: value => value.every(or(isString, isNumber, isGeoJSONFeature)),

To Reproduce
Steps to reproduce the behavior:

1. Use <vl-source-vector> component which load GeoJSON GeometryCollection geometry type data and <vl-interaction-select> component.

Example:

   <!-- POI vector layer -->
    <vl-layer-vector :id="poiLayerId">
      <vl-source-vector
        :wrap-x="true"
        :loader-factory="poiFeaturesLoader"
        :strategy-factory="loadingStrategyFactory"
        :attributions="attributions"
        :ref="poiLayerId"
      >
        <vl-style-func :factory="poiFeatureStyleFuncFactory" />
      </vl-source-vector>
    </vl-layer-vector>

    <vl-interaction-select
      :features.sync="selectedFeatures"
      ref="selectPoiFeature"
      :hitTolerance="hitTolerance"
      :filter="filterPOILayer"
    >
      <vl-style-func
        :factory="selectedPoiFeatureStyleFuncFactory"
      ></vl-style-func>
    </vl-interaction-select>

3. Click on the feature on the map.
4. See error inside web browser console

Error:

19:47:00.398 [Vue warn]: Invalid prop: custom validator check failed for prop "features".

Expected behavior
<vl-interaction-select> component should be properly validate feature property if it is GeoJSON GeometryCollection geometry type.

Additional context:
For validation GeoJSON GeometryCollection geometry coordinates type is correct path feature.geometry.geometries[0].coordinates

vuelayers/src/ol-ext/format.js

Line 350 in 6dc131f

isArray(geometry.coordinates)

Example of a GeometryCollection:

{ "type": "GeometryCollection",
"geometries": [
  { "type": "Point",
    "coordinates": [100.0, 0.0]
    },
  { "type": "LineString",
    "coordinates": [ [101.0, 0.0], [102.0, 1.0] ]
    }
 ]
}
