Opaque per-view configuration for the Map view type.
The host stores and round-trips this blob verbatim against the active ViewTypeID and never
inspects it — only this renderer reads/writes it. It carries the two pieces of map state that
should persist with the view: the render mode (point / boundary / choropleth / heatmap) and the
last display state (zoom / center / clustering / choropleth options). Both are optional so a
freshly-created Map view starts from sensible defaults.
