Adds choropleth plot support to plotly-express with full support for live,
ticking tables. Includes:

  • New choropleth, choropleth_map, and (deprecated) choropleth_mapbox APIs
  • Remap color -> z in data mapping for choropleth trace types so live
    updates target the correct trace field
  • Skip the default {lat:0, lon:0} center for geo-based plots; that center
    conflicts with projections like 'albers usa' and crashes the JS renderer
  • Unit tests for the new APIs and updated geo-plot test expectations
  • Docs pages and sidebar entries
  • E2E fixtures and spec covering static and ticking choropleth widgets
