      Description

      The following commit to spark removed support for decimal binary types: https://github.com/apache/spark/commit/9c29c557635caf739fde942f53255273aac0d7b1#diff-7bdf5fd0ce0b1ccbf4ecf083611976e6R428

      As per the parquet spec, decimal can be used to annotate binary types, so support should be re-added: https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#decimal
