Method for creating new directory object w/ set of links

Given a list or iterable of `{"Hash": CID, "Name": str}` objects, it should be possible to create a new directory object using `object.put` without having to manually create the directory object in bytes, query the size of links, or recursively add single links to directories one at a time (creating intermediate objects). Not sure if I'm missing an API for how to do this, but it would be pretty helpful.
