Skip removal of Mux assets when deleting duplicated assets #68
Description
- Only delete a Mux asset if there are no other local assets around referencing it
- Currently, deleting a local asset will delete its associated Mux asset
- This is fine unless the deleted asset was itself duplicated from another asset & both reference the same Mux ID
- Requires [6.x] Prototype of an asset reference viewer statamic/cms#13832 for a simple implementation
