It silently ignored the out-of-order projection, i.e.
```
#[test]
fn test_out_of_order_projection() {
let testdata = arrow::util::test_util::parquet_test_data();
let path = format!("{}/alltypes_plain.parquet", testdata);
let file = File::open(&path).unwrap();
let reader = SerializedFileReader::try_from(file).unwrap();
let expected_rows = reader.metadata().file_metadata().num_rows() as
usize;
let mut arrow_reader = ParquetFileArrowReader::new(Arc::new(reader));
let b1 = arrow_reader.get_record_reader_by_columns([0, 1],
2).unwrap();
let b2 = arrow_reader.get_record_reader_by_columns([1, 0],
2).unwrap();
assert_eq!(b1.schema, b2.schema);
}
```
Would pass
