Allow for polygons to be styled with a point symbolizer

[rdewit]

Description

This proof of concept PR aims to allow for polygons to be styled with point symbolizers.

I'm not sure if this is the right approach to take and look forward to feedback.

Example:

symbolizers: [
  {
    "kind": "Mark",
    "radius": 15,
    "opacity": 0.2,
    "color": "#0055ff",
    "wellKnownName": "Circle",
    "strokeColor": "#ffffff",
    "strokeWidth": 3,
    "strokeOpacity": 1
  },
  {
    "kind": "Icon",
    "image": "https://upload.wikimedia.org/wikipedia/commons/thumb/5/5f/Parking_icon.svg/128px-Parking_icon.svg.png",
    "size": 0.1,
    "rotate": 0,
    "opacity": 1
  },
  {
    "kind": "Text",
    "label": "Ward: {{WARD_NAME}}",
    "color": "#494f99",
    "haloWidth": 2,
    "haloColor": "#f7f7f9",
    "rotate": 0,
    "size": 12,
    "font": [
      "Verdana"
    ],
    "offset": [
      0,
      28
    ]
  }
]
