Built Controls For Color By Category

[lhawkman27]

Summary/Description

We need to build out controls for the ColorByCategory functionality.
This will replace the colorByCategory styling block in our current JSON Blob control.

• Dimension selector.
• Category color mapping UI.
• Default/null category labels.
• Category enable/disable behavior.

"colorByCategory": {
    "categoricalColors": [
      {
        "No Visible Damage": {
          "fillColor": [52, 168, 83, 255],
          "legend_entry_name": "No Visible Damage"
        }
      },
      {
        "Inaccessible": {
          "fillColor": [66, 133, 244, 255],
          "legend_entry_name": "Inaccessible"
        }
      },
      {
        "Affected": {
          "fillColor": [178, 134, 207, 255],
          "legend_entry_name": "Affected"
        }
      },
      {
        "Minor": {
          "fillColor": [245, 166, 35, 255],
          "legend_entry_name": "Minor"
        }
      },
      {
        "Major": {
          "fillColor": [220, 53, 69, 255],
          "legend_entry_name": "Major"
        }
      },
      {
        "Destroyed": {
          "fillColor": [0, 0, 0, 255],
          "legend_entry_name": "Destroyed"
        }
      },
      {
        "Other": {
          "fillColor": [128, 128, 128, 255],
          "legend_entry_name": "Other"
        }
      }
    ],
    "defaultLegendName": ["Other"],
    "dimension": "damage_summary"
  },

dimension control: column selector

categoricalColors controls section:
Need some sort of addition control button that allows users to add category entries they want.
category name control - text entry
fillColor control: RGBA Selector or field entries (for R,G,B,A)
legendEntryName control: text entry

defaultLegendName control: text entry

Motivation/Context

The JSON blob has been useful as a fast prototyping surface, but it is now carrying too much product behavior: category coloring, metric coloring, point sizing, legends, text overlay, styling, defaults, maybe more. That makes it hard for users, hard to validate, and easy for MVT/non-MVT behavior to drift.

Acceptance

• ColorByCategory works as expected.
• Point/Line/Polygon/GeoJSON and MVT all receive the same category config.
• Update documentation properly (Wiki, etc...)
