5.2.0

Minor release supporting Vega 5.6 and adding some previously missing functions.

Additions

• kdResolve and associated reShared and reIndependent functions for resolving multiple densities in a KDE transform.
• bnSpan for setting the span over which bins are calculated.
• equalEarth core map projection added.
• identityProjection and associated reflectX and reflectY map projection functions added.
• leBorderStrokeDash for configuring legend border dash style.
• cfSignals for supporting configuration signals (Vega 5.5).
• cfEventHandling and associated cfe functions for more flexible Vega 5.5 event configuration.
• description top-level metadata option (previously inadvertently hidden).
• userMeta top-level custom metadata options.

Deprecations

• cfEvents deprecated in favour of cfEventHandling [cfeDefaults ...]

Bug Fixes

• cfGroup mark properties now correctly creates literals rather than objects (e.g. "fill": "#eee" rather than "fill":{"value":"#eee"}).

Other Changes

• Minor improvements to the API documentation.
• Update examples to use Vega-embed 5 and Vega 5.5 runtimes
• Minor additions to tests.
