fix a few wrist tracker issues and introduce SGWristTrackerVisualizationComponent

CHANGELOG.md

@@ -24,6 +24,7 @@ This is a minor release focusing mainly on bringing OpenXR-compatible hand track
 - Added USGVirtualHandComponent::OnHandVisibilityChanged() event in order to notify other components/actors whenever the virtual hand mesh appears or disappears (for example, this could happen when a glove is connected/disconnected).
 - Added USGWristTrackerComponent::GetMotionControllerData().
 - Added USGWristTrackerComponent::OnWristDeviceVisualTypeChanged event in order to be able to notify other components/actors whenever the wrist-tracking device switches between hand tracking or motion controllers.
+- Added SGWristTrackerVisualizationComponent which is replacing UXRDeviceVisualizationComponent usage inside SGPawn.
 - Added the SenseGloveDebugKismet module in order to allow drawing of debugging gizmos and virtual hands from Blueprint.
 - Added a new static Draw() method overload to DebugGizmo which allows passing an FQuat instead of a FRotator.
 - Added SGEngineUtils.
