parquet-pig should not throw an exception reading a timestamp from impala file

Hi, I need to load impala table with timestamp columns with pig. I think loading timestamp cols is still a NYI feature. Waiting for [#218](https://github.com/Parquet/parquet-mr/issues/218) TBD, pig-parquet should not throw an exception but at least should bind Int96 into a bytearray (users can write their own UDF to convert it into pig datetime type).
Is there anyone working on that?

Start by tracing parquet-pig's timestamp reader with an Impala file containing Int96 columns, and review issue #218 for the pending timestamp context. Done means reading the file no longer throws an exception and exposes Int96 as a bytearray for downstream UDF handling.
