v0.1.14

Changelog

Added

• Added EXT_splat_opacity support for SPZ-compressed Gaussian splat
  primitives so tiles can carry Spark-compatible per-splat opacity values in a
  FLOAT / SCALAR accessor.
• Added an EXT_splat_opacity extension note describing the extension shape,
  accessor requirements, and value semantics.

Changed

• Split Gaussian splat fade handling and splat opacity extension loading into
  focused helper modules.
• Applied EXT_splat_opacity values before Spark texture creation so the
  decoded splat data includes overrides during initial upload.
