> - provide a convenience function FormatValue() to complement ParseValue()
> - parameterize both parsing and formatting with the corresponding DataType
> subclass (for example a formatting or parsing a timestamp requires a TimeUnit
> and this can be derived from a TimestampType)
> - rename StringConverter and StringFormatter to ParseValueTraits and
> FormatValueTraits, to emphasize the convenience functions as the preferred
> interface
> - ParseValue should accept a string_view for simplicity, and an overload
> should be provided which returns an optional<>
