>  Tighten up EOF bounds checking in LazyBinaryDeserializeRead so bytes beyond stated row
end are never read.  Use WritableUtils.decodeVIntSize to check for room ahead like regular
LazyBinary code does.
> Display more detailed information when an exception is thrown by DeserializeRead classes.
> Add Unit Tests, including some designed that catch the errors like HIVE-13818.
