Same as above.

> When trying to perform a conversion of a field between a String and a byte
> array, various errors are reporting (depending on where the conversion is
> taking place). Here are some examples:
> 1) CSVReader, if a column with String values is specified in the schema as
> "bytes"
> 2) ConvertRecord, if an input field is of type String and the output field is
> of type "bytes"
> 3) ConvertRecord, if an input field is of type "bytes" and the output field
> is of type "String"
> Many/most/all of the record components use utility methods to convert values,
> I believe these methods need to be updated to support conversion between
> String and byte[] values.
