Description
Called when an unreferenced I/O store chunk is loaded via the I/O dispatcher interface. This happens when the package loader has resolved the package store entry or when requesting unstructed data via FBulkData.
Note: In shipping builds the on-demand install cache will return 'NotInstalled' and fail the request when trying to load an unreferenced I/O store chunk. Return 'UnknownChunkID' to let lower priority I/O dispacher backends handle the I/O request.
