Alerts/ Support Multipoint

[ximenabb]

The front-end code (PR#844) supports displaying alerts of type Point, LineString, MultiLineString, Polygon and MultiPolygon.
It does not support MultiPoint

ToDo

• Add support of MultiPoint

Haven't tested it, but I think this is all that's required in src/frontend/screens/MapScreen/MapLayers/RemoteDetectionAlertsLayer.tsx:

We could do it the way that Evan has recommended, the only thing is that it would be in-distinguishable from normal points. Does the CMI team want them styled differently (aka Not red dots) from the other alerts?

[ximenabb]

@ErikSin they can be the same style (red dot) as other alerts

[gmaclennan]

Yes, generally there should be no need to style Multi geometry variants differently than their non-multi versions, e.g. Line and MultiLine should be the same, Polygon and MultiPolygon should be the same, and Point and MultiPoint should be the same.
