Use more often the new parquet reader

    Details

      Description

      The choice of using the regular parquet reader of the optimized one is based of what type of columns is in the file. But the columns that are read by the query doesn't matter. We can increase a little bit the cases where the optimized reader is used by checking is the projected column are simple or not.
      This is an optimization waiting for the fast parquet reader to handle complex structure.
