Implements read path for the date type in ORC scanner. The internal representation of a date is an int32 meaning the number of days since Unix epoch using proleptic Gregorian calendar. Similarly to the Parquet implementation (IMPALA-7370) this representation introduces an interoperability issue between Impala and older versions of Hive (before 3.1). For more details see the commit message of the mentioned Parquet implementation.
