Buffers make more sense for this function because one of their primary use cases is working with bytes. The tuple implementation was an array of floats, which is less performant and ergonomic for common operations. (i.e: bit manipulation) Buffers also have the advantage they are mutable, meaning the user can write ints to an existing buffer.
