Doesn't make much sense since we cannot factor the second order filter function into control matrices as in the first order case. In princinple, one can still loop the integration over one basis axis, but this is a bit tedious and not pretty to implement, so we leave it for now.

This adds functionality to compute the second order of the Magnus expansion, allowing exact results for the quantum process for Gaussian noise.
