[unity] Added Preferences setting `Reload SkeletonData after Play`, disable to avoid the reloading delay after exiting play-mode.

CHANGELOG.md

   * Added `SkeletonRootMotion` callback delegates `ProcessRootMotionOverride` and `PhysicsUpdateRootMotionOverride` to customize how root motion is applied. The new property `disableOnOverride` determines whether the callback will be issued in addition or instead of normally applying root motion. Added property `rootMotionScaleRotation` to allow scaling rotational root-motion to match e.g. a 90 degree rotation to a custom target angle.
   * Added outline shader parameter `Advanced - Opaque Alpha` which can be used to exclude problematic semi-transparent areas, which may receive an undesired large outline color overlay otherwise.
   * Added Spine Preferences setting `Prefabs` - `Optimize Preview Meshes`. When enabled, Spine prefab preview meshes will be removed in a pre-build step to reduce build size. This increases build time as all prefabs in the project will be processed. Defaults to false to not slow down builds substantially every time.
+  * Added Spine Preferences setting `Reload SkeletonData after Play`. When enabled, the shared `SkeletonData` of all skeletons in the active scene is reloaded (from the `.json` or `.skel.bytes` file) after exiting play-mode. You can disable this setting to avoid the reloading delay if you can ensure that there are no (accidental) modifications to the shared `SkeletonData` during play-mode (otherwise it would carry over its effect into subsequent plays). Defaults to `true` (the safe setting), which maintains existing behaviour. 
  
 * **Breaking changes**
   * Made `SkeletonGraphic.unscaledTime` parameter protected, use the new property `UnscaledTime` instead.
