changed to batch-skip instead of resizing buffer, as per @pitrou suggested (I had to reduce the buffer size to 64 Bytes to make the tests actually doing multiple batches of skips, because the number of buffered rows is always less that [kMinLevelBatchSize](https://github.com/apache/arrow/blob/main/cpp/src/parquet/column_reader.cc#L1369)). for BatchSize less than 512, the improvement is still there. For BatchSize `1000` and `5000`, the median time slightly increased to `78554904` and `74765553`. -- This is an automated message from the Apache Git Service.
