> Should be pretty straightforward to support:
> 1. Add getInterval accessor to InternalRow.
> 2. Use two longs in the variable length portion of UnsafeRow to store the interval data.
> 3. Add IntervalWriter to UnsafeRowWriters.
> 4. In GenerateUnsafeProjection, add support for IntervalType, using the newly added UnsafeRowWriters.IntervalWriter.
> 5. Change BoundReference to use the specialized getter for IntervalType.
> 6. Update the accessor for codegen in CodeGenerator.
