SnowflakeIO fails to recognize new-line char in a column

When a  snowflake string column contains new-line, the snowflakeIO fails to read it as a record. Instead two invalid records gets created.

I see the issue due to the usage of TextIO; as the exported extract from the snowflake contains the column data enclosed with quoted string, making it a valid CSV.

Possibly be solved if FileIO(with custom splitable dofn to handle big file) is used instead of TextIO.
