ColourInfo interface

Colour information for a raw video stream, as named values (the SDK maps them to the wire’s H.273 code points, or Norsk-private code points for the camera curves/gamuts H.273 cannot express — e.g. "logc4" + "arri-wide-gamut-4" for ARRI footage). Set on StreamMetadataOverrideSettingsUpdate to force a source’s colour metadata (e.g. BT.709) so it matches its siblings and avoids a downstream switch seeing a colour-context change — or to declare camera-log input so downstream colour processing linearizes it correctly.
