Add spots_by_place_ids option

I assume that I have a pretty common use case where I'm storing place_ids and want to pull in place details for 20 places at once with a single API query (the max allowed by the API) rather than doing a separate API call for each place. I don't see a way to do that currently with the gem (which is otherwise great, by the way). Am I missing something? Or can that functionality be added?
