FocusEntity Versions Save

Set the ARView reference to a weak variable, avoiding memory leaks.

Minor fixes:

• Better tracking with LiDAR devices
• Smooth transitions between two vertical surfaces

@Reality-Dev has added a couple of enhancements in this release:

• You can now apply textures to FocusEntity using the .colored style (Usage in Example)
• FocusEntity will smoothly change position and orientation, check isChangingAlignment to see its state.

Applying the colored style previously did not work, thanks for flagging @vegiwoo

• Cannot use this class if you cannot import ARKit, but it will at least let your app build now

• Just one class with multiple styles
• No more dependency on SmartHitTest.
• Using Raycast instead of hitTesting
• Methods for destroying added
• Methods for moving between ARViews

• Change access modifier on setAutoUpdate to public

• Added option to have the FocusEntity auto-update, no more need to ARSessionDelegate to update position.

Using a camera anchor for positioning the FocusEntity when in initializing state

No changes in terms of compatibility or use, should just run a little smoother.

• Call the delegate functions after the anchor and position have changed
