Is your feature request related to a problem or challenge? Please describe what you are trying to do.
I would like to generate statistics on how many rows pass a particular filter that was evaluated to BooleanArray

I know there are very fast ways to do this within the arrow codebase but I didn't see any good way to use them externally

Describe the solution you'd like
Optimized functions on BooleanArray

Describe alternatives you've considered
Use lower level Buffer apis
