Description
From atrivedi's benchmark finding:
2) Materialize values from Validity and Value direct buffers instead of
calling getInt() function on the IntVector. This is implemented as a new
Unsafe reader type (
https://github.com/animeshtrivedi/benchmarking-arrow/blob/master/src/main/java/com/github/animeshtrivedi/benchmark/ArrowReaderUnsafe.java#L31
)
3) Optimize bitmap operation to check if a bit is set or not (

)
