Creates a vector whose length is length and iterates across each index k between 0 and length, applying f at each iteration to the current index and current states, in that order, to receive n + 1 values: the bit to put in the kth slot of the new vector and new states for the next iteration. On the first call to f, the states' values are the seeds.
