MC WFS with more gain
Quick update: we found that the reason for the MC WFS instability was that the digital anti-whitening was one but not the analog whitening.
We turned off the digital filters and were able to increase the gain by a factor of ~30. It is left like this, but if it hampers IFO locking then best to just turn it back down to an overall gain of 0.1 or 0.05.
