[AVRO-2748] python schema resolution occurs on every read

Description

In python, the schema resolution appears to be happening on each read operation. I'm not an avro expert but in my perusing through the python io code I haven't yet noticed a reason that the schema resolution couldn't happen once up front, during the construction of DataFileReader, when it first loads the write_schema.
