FM6 and FM10 of LSC-MC were restored
During tonight's locking work, I realized that FM6 and FM10 (both resonant gains around 20Hz) were actually activated by cm_step.
So I restored those filters from the svn history.
Instead, I removed a bunch of unused filters from LSC-DEMOD and LSC-DEMOD_A (moving zero filters) to off load c1lsc.
As for the locking itself, the DARM loop becomes unstable at around arm power = 30. I may have to add a filter to give a broader phase bubble.
