  +##### Breaking Changes :mega:
  +
  +- Deprecated parts of the old Blueprint API for feature ID attributes from `EXT_feature_metadata`.
  +
  +##### Additions :tada:
  +
  +- Added a Blueprint API to access feature ID textures and feature textures from the `EXT_feature_metadata` extension.
  +- Improved the Blueprint API for feature ID attributes from `EXT_feature_metadata` (and upgraded batch tables).
  +- Added the `UCesiumEncodedMetadataComponent` to enable styling with the metadata from the `EXT_feature_metadata` extension. This component provides a convenient way to query for existing metadata, dictate which metadata properties to encode for styling, and generate a starter material layer to access the wanted properties.
  +- Added two example metadata styling materials for the NYC buildings tileset.
  +
  ##### Fixes :wrench:
  - glTF normal, occlusion, and metallic/roughness textures are no longer treated as sRGB.
