List a collection's places

The places a collection has found, oldest first, so a page you have already read stays the same as more arrive. Each place says whether we already had it, which is how you check what you were charged. A page can come back short when a business asked to be left out, so keep reading until you pass the total rather than stopping at a short page. The collection's counts still include those places, which is the record of what you were charged. Needs an API key. Costs no credits.
