Function bitwise_bin_op_helper

pub fn bitwise_bin_op_helper<F>(
    left: &Buffer,
    left_offset_in_bits: usize,
    right: &Buffer,
    right_offset_in_bits: usize,
    len_in_bits: usize,
    op: F,
) -> Buffer
where
    F: FnMut(u64, u64) -> u64,

Apply a bitwise operation op to two inputs and return the result as a Buffer. The inputs are treated as bitmaps, meaning that offsets and length are specified in number of bits.
