> ORC's SerDe currently does nothing, and hence does not calculate a raw data size.  WriterImpl, however, has enough information to provide one.
> WriterImpl should compute a raw data size for each row, aggregate them per stripe and record it in the strip information, as RC currently does in its key header, and allow the FileSinkOperator access to the size per row.
> FileSinkOperator should be able to get the raw data size from either the SerDe or the RecordWriter when the RecordWriter can provide it.
