- Updated some ARReferenceObject APIs based on their (better) Swift names. Breaking changes but on new APIs.
- Update ARReferenceObjectTest for device (center and extent have real values on device).
- Reuploaded an arobject file from Beta 3 just in case because of: "ARReferenceObject and ARWorldMap data generated using iOS 12 beta 2 or earlier isn’t compatible with beta 3 or later. Please rescan your objects to generate new ARReferenceObject and ARWorldMap data."
I obsoleted `GetProjectPoint` in favor of `Project` because of the introduction of `Unproject` (which made me realize the naming was wrong) and based on the API doc https://developer.apple.com/documentation/arkit/arcamera/2923538-projectpoint?language=objc.
The `CGPoint` returned is the projection of a point. An other naming option would have been `GetProjectedPoint` but I think `Project` is closer to the original and clear enough. You project/unproject something onto something else and you get the projection back.
