Ways to attach metadata to an embedding

E.g. url, token_count. Small-ish amounts of storage next to an embedding that are persisted across runs.

You could approximate it if embeddings whern used as a property name are converted into a hash of their text or something.

Ideally it should be possible to attach arbitrary types and even query it. Use cases: home-grown ACLs, "filename" grouping of embeddings, etc.
