Built Controls For Dynamic Point Size

[lhawkman27]

Summary/Description

We need to build out controls for the the dynamic point size scaling This will replace the pointSize block in our current JSON Blob control. Note: Dynamic Point Size can either be a single value (for global pointSize) or a config block {}

• Value column selector.
• min/max size.
• lower/upper bounds.

Either be this:

"pointSize": 8

or this:

"pointSize": {
    "valueColumn": "incident_size",
    "startSize": 4,
    "endSize": 30,
    "lowerBound": null,
    "upperBound": null
  }

valueColumn: column dropdown selection
startSize control: number text entry or dropdown with a limit of 30
endSize control number text entry or dropdown with a limit of 30
lowerBound control: number text entry
upperBound control: number 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

• Point layers and MVT point sublayers can consume the same size config.
• Update docs
