> [Rust]: Benchmark and improve count_set_bits function
> -----------------------------------------------------

> `count_set_bits` and `count_set_bits_offset` currently use a lookup table for
> each byte. I'm thinking it should be more efficient to iterate the data in
> larger chunks and use the builtin `count_ones` function.
