Fraction to the boundary from (current) slacks for a given step in the slacks.

Usually, one will use the primal_frac_to_the_bound method to compute the primal fraction to the boundary step size, but if it is cheaper to provide the steps in the slacks directly (e.g. when the primal step sizes are only temporary), the this method is more efficient. This method does not cache computations.
