GeoJson vector-tile dynamic styling

[nf-s]

What this PR does

• EPIC Client-side vector support #4633
• Opacity slider support for GeoJSON #5767
• Specifying stroke-opacity for geojson polygons in init files does not work #5870
• GeoJsonMixin forceLoadMapItems needs rewrite #5275
• Drag and drop shapefiles turn into vector tiles in the browser #3082
• Support styling of vector features #574
• partially Support opacity/transparency in vector layers such as WFS, GeoJSON, CSV, CZML. #1442
• Generate legend for GeoJSON files without styling #1353
• V7 - V8: Support opacity slider for GeoJSON in v8 #5044

• GeoJsonMixin.style["stroke-opacity"] will now also set polygonStroke.alpha and polylineStroke.alpha (Specifying stroke-opacity for geojson polygons in init files does not work #5870)
• Reduce GeoJsonMixin default stroke width from 2 to 1
• Add TableMixin styling to GeoJsonMixin - it will treat geojson feature properties as "rows" in a table - which can be styled in the same way as TableMixin (eg CSV). This is only enabled for geojson-vt/Protomaps (which requires Terria.configParameters.enableGeojsonVt = true). For more info see GeojsonMixin.forceLoadMapItems()
  • This can be disabled using GeojsonTraits.disableTableStyle
• Opacity and splitting is enabled for Geojson (if using geojson-vt/protomaps)
• Replaced @types/geojson Geojson types with @turf/helpers
• In GeojsonMixin replaced with customDataLoader, loadFromFile and loadFromUrl with forceLoadGeojsonData
• GeojsonMixin will now convert all geojson objects to FeatureCollection
• Exporting GeojsonMixin will now add proper file extensions
• WebFeatureServiceCatalogItem and SocrataMapViewCatalogItem now uses GeoJsonMixin All Catalog items should use GeojsonMixin instead of creating GeoJsonCatalogItems #5380
• Fix ProtomapsImageryProvider geojson feature picking over antimeridian
• Add Socrata group to "Add web data"
• Added "marker-stroke-width", "polyline-stroke-width", "polygon-stroke-width" to GeojsonStyleTraits (Note these are not apart of simplestyle-spec and can only be used with geojson-vt)
