com.unity.xr.visionos 0.7.1 Package Notes

Added a step to the build pre-processor which disables splash screen on visionOS player builds.
Enabled foveated rendering for VR builds on Unity 2022.3.16f1 and above.
Added extension method `TryGetVisionOSRotation` to `XRHandJoint` when using the `UnityEngine.XR.VisionOS` namespace. If you depended on the rotations reported before this version, use this `TryGetVisionOSRotaiton` instead of the rotation reported from `XRHandJoint.TryGetPose`.

Changed the platforms behavior to report rotations of hand joints through `XRHandSubsystem` that align more closely with OpenXR's rotations. If you depended on the previous reporting of rotations, use the rotation reported by `TryGetVisionOSRotation`, a new extension method to `XRHandJoint`.
All packages now require 2022.3.15f1 and later (rather than 2022.3.11fa and later) to pick up fixes for various memory leaks made in 15f1.
### Deprecated

Support for Unity versions earlier than 2022.3.11f1.
Removed gray "Loading..." window in VR builds. VR apps now launch directly into the immersive space.

Fixed a linker error in Xcode when building the visionOS player with App Mode set to VR, but the visionOS loader is not enabled.
Fixed a memory leak in `VisionOSHandProvider`.
Fixed a memory leak caused by using particle systems in VR mode.
Implemented lifecycle management. Unity now suspends and resumes properly when the home menu is brought forward.
Fixed an issue where closing the gray "Loading..." window would mute audio.
Fixed an issue where spatial audio would use the gray "Loading..." window as its source location.
