[Rust] StreamReader, read_dictionary duplicating schema info #26731
Description
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!
