Styling GeoJSON Simple Style Spec

[geospatialmapmashup]

GeoJSON
https://docs.terria.io/guide/connecting-to-data/catalog-type-details/geojson/
style

An object of style information which will be used instead of the default, but won't override styles set on individual GeoJSON features. Styles follow the SimpleStyle spec: https://github.com/mapbox/simplestyle-spec/tree/master/1.1.0 marker-opacity and numeric values for marker-size are also supported.

I know that GeoJSON.io and other sites can write MapBox Simple Style as part of the GeoJSON

Do you have any example catalogs for us to see the best approaches of handling this
I want to handle this at Catalog Level
unless we really need different features styled differently

It is basically

{
  "catalog": [
    {
      "name": "Point",
      "type": "geojson",
      "url": "https://gist.githubusercontent.com/steve9164/c517308cf52638e1ff3a2992e5aec3d1/raw/b53d846db4e870dca1681332db40962689aa7c35/point.geojson",
      "style": {
        "marker-url": "http://ci.terria.io/master/images/terria_logo.png"
      }
    }
  ]
}

Shamelessly lifted from @steve9164 and his gist

I also found https://raw.githubusercontent.com/TerriaJS/terriajs/master/wwwroot/test/GeoJSON/test-styles.geojson and didn't realise we could do this. Very cool!
