Review Comment:
I think you can remove this, and `case (DecimalType(), v:
java.math.BigDecimal) => writer.writeCharacters(v.toString)` (See also
`JacksonGenerator` and which types are being handled).
BTW, we would also add the type supports for `TimestampNTZType`,
`YearMonthIntervalType` and `DayTimeIntervalType`. But they are orthogonal and
can be done separately.
