Function croaring_sys::array_container_grow

pub unsafe extern "C" fn array_container_grow(
    container: *mut array_container_t, 
    min: i32, 
    max: i32, 
    preserve: bool
)

increase capacity to at least min, and to no more than max. Whether the existing data needs to be copied over depends on the value of the "preserve" parameter. If preserve is false, then the new content will be uninitialized, otherwise the original data is copied.
