Document maximum size for autometadata fields #682
Description
In https://github.com/kbase/workspace_deluxe/blame/develop/docsource/typedobjects.rst#L345, provide a link to the limits documentation (https://github.com/kbase/workspace_deluxe/blob/develop/docsource/limits.rst) and note that autometadata fields are subject to the same limits as normal metadata, and so care should be taken in which fields are chosen.
