> The `read_dictionary` function takes both an ipc schema and a `Schema`, but it can get the information it needs from just the `Schema`. Then the `StreamReader` doesn't need to keep the ipc schema bytes around, because it also has the `Schema`.
> The Flight integration test code needs to read dictionaries as well, and it seemed overly complex to need both kinds of schemas. PR coming!
