> When casting given string datum to specified type, CSV should return {{null}} for nullable types if {{datum == options.nullValue}}.
> However, for certain data types like {{Boolean}}, {{TimestampType}}, {{DateType}}, CSV in 2.0 does not return {{null}} for some "empty" datum. This is a regression comparing to 1.6.
