Allow users to enable dictionary column reads from parquet files

Describe the solution you'd like

Add a config flag that lets users opt in to reading Parquet string columns as Arrow DictionaryArray instead of plain Utf8.

This config should be threaded through arrow-rs to parquet reader configs.

This config should not just convert any given string column into a dictionary array. It should merely give the engine the option to interpret string columns as dictionary arrays if it chooses to.
