Review Comment:
The default logic currently will enable dictionary encoding, but if you want
to be explicit you can use the writer property
`parquet.WithDictionaryFor("path.to.column", true)` or
`parquet.WithDictionaryDefault(true)` to explicitly tell the writer to use
dictionary encoding when writing the column.
