Description

LazyBinarySerDe.serialize() ends up making getCategory()/getPrimitiveCategory() calls for every column of every row. Tried some simple tests to eliminate these calls for the non-vectorized version, this looks like it speeds up the writes by ~3x.
Adding a LazyBinarySerDe2 class with this new implementation.
