parquet::record::RowIter cannot be customized with batch_size and defaults to 1024

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
I'd like to read parquet file with custom batch_size using parquet::record::RowIter

Describe the solution you'd like
Allow custom tree builder for parquet::record::RowIter

Describe alternatives you've considered
replace parquet::record::RowIter with own implementation

Additional context
SerializedFileReader::get_row_iter and SerializedRowGroupReader::get_row_iter returns parquet::record::RowIter, so I cannot set custom batch_size to the result anyhow
