crosperf: Remove benchmark scipy dependency At present, we use scipy.norm's isf function (inverse survival function). This commit introduces a hand-rolled replacement that uses a numerical interpolation technique to compute the inverse survival function. Testing this automatically is not easy if we wish to remove scipy, but with 0.01 pitch, we see about 4 digits of accuracy. Mind you, we do not handle the infinite cases, but this is not a problem for the use case presented in this function.
