Function croaring_sys::roaring64_bitmap_add_many

pub unsafe extern "C" fn roaring64_bitmap_add_many(
    r: *mut roaring64_bitmap_t,
    n_args: usize,
    vals: *const u64
)

Add n_args values from vals, faster than repeatedly calling roaring64_bitmap_add()

In order to exploit this optimization, the caller should attempt to keep values with the same high 48 bits of the value as consecutive elements in vals.
