Description

The CSVInputFormats have only FieldParsers for Java's primitive types (byte, short, int, long, float, double, boolean, String).

It would be good to add support for CSV field parsers for custom data types which can be registered in a CSVReader.
We could offer two interfaces for field parsers.

1. The regular low-level FieldParser which operates on a byte array and offsets.
2. A StringFieldParser which operates on a String that has been extracted by a StringParser before. This interface will be easier to implement but less efficient.
