Is it possible to support the between operator for SparkDateTime UDT

[hbutani]

A predicate like 'dateTime(o_orderdate) between dateTime("1995-01-01") and dateTime("1996-12-31")'
gives the following error.

org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 18.0 failed 1 times, most recent failure: Lost task 0.0 in stage 18.0 (TID 1961, localhost): java.lang.RuntimeException: Type org.sparklinedata.spark.dateTime.SparkDateTimeUDT@52d6ab8c does not support ordered operations
