OpfsPersister
The OpfsPersister interface represents a Persister that lets you save and load Store data to and from a file in an origin private file system (OPFS).
You should use the createOpfsPersister function to create an OpfsPersister object.
It is a minor extension to the Persister interface and simply provides an extra getHandle method for accessing the file the Store is being persisted to.
