Feature: add PreserveViewport as a prop for google-kml-layer

[zeroedin]

Is your feature request related to a problem? Please describe.
Not a problem per say but having to work around it I guess is an annoyance.

I realize you all are working on the version for vue3 and this is most likely the last of your worries. But would be nice to see it incorporated if possible in future versions if anything. I myself have not yet moved to vue 3.

Describe the solution you'd like
Would like to be able to preserveViewport when adding KML to a map with a prop.

<GmapMap id="gmap" ref="mapRef" :center="center" :zoom="zoom" :options="options">
  <google-kml-layer :url="kml" :clickable="false" preserveViewport="true" />
</GmapMap>

Describe alternatives you've considered
This is my work around

  async mounted(){
    await this.$gmapApiPromiseLazy();
    this.$refs.mapRef.$mapPromise.then((map) => {
      new this.google.maps.KmlLayer({
        url: 'https://url-to-kml.com/my.kml',
        preserveViewport: true,
        map: map
      })
    })
  }
