com.unity.entities 1.2.0 Package Notes

Document counterintuitive behavior when an `EntityQueryMask` is created from an `EntityQuery` that includes a `WithNone()` constraint, where `T` is an `IEnableableComponent`.

Performance improvements in `LocalToWorldSystem` when processing entities with non-dirty hierarchies and no children.
### Deprecated
`EntityManager.CopyEntities()` is now deprecated, and will be removed from the public API in a future package release. We're not aware of any use cases for this function outside of the Entities package itself; `EntityManager.Instantiate()` is the correct way for higher-level code to instantiate copies of existing entities.

BakingAnalytics no longer initializes TypeManager [InitializeOnLoad]
Fixed issue where breakpoints in jobs defined after systems with SystemAPI usage are not hit.
Fixed an error where the Entities Hierarchy window was accessing a destroyed world during UI bindings.
Using SystemAPI.GetComponentRO/RW with "using static SystemAPI" within an Entities.ForEach used to confuse the code generator and failed to compile.
Replace `HierarchyNodeMap`'s indexer setter with explicit add/update logic.
an issue with hybrid entity baking regarding scales with different signs
Entities Hierarchy now removes all nodes of a scene and subscenes when the scene is unloaded.
Exception thrown when entering a prefab from the Entities Hierarchy
Fixed: Memory leak in certain circumstances in Entity Scene Streaming
Improved error message for when `SystemAPI.QueryBuilder` users forget to call `.Build()`.
An assert when using AddMultipleComponentsDuringStructuralChange with more than 10 entities in some cases
Add filter button was not showing filters in Archetypes and Journaling windows.
An invalid range check caused the removal of entities from the hierarchy view to sometimes fail in perfectly valid cases.
