Not yet implemented: Decoding Int32 "PlainDictionary"-encoded optional parquet pages

[mdrach]

Hey, I encountered an issue similar to this one. Hit during

            let arrays =
                column_iter_to_arrays(pages, types, field.clone(), None, row_group.num_rows())?;

pages is one of the pages in this file.

Error:

Not yet implemented: Decoding Int32 "PlainDictionary"-encoded optional  parquet pages. 

Hope the fix is straightforward like the fix for the other issue. Please let me know if I can provide any additional information.

Using arrow2 0.17.0.
