This adds a aliasing view and loop rate param:
When selected the whole frequency range is folded down into the niquist of the loop rate, this represents the noise the control loops actually see. For example this is the normal sub 200hz:
With aliasing on:
The extra peaks are reflections from higher frequencies:
There is also the option to show only the aliasing, this removes the frequencies lower than the niquist and only shows the aliased signals reflected down from higher frequencies, this should be as close to 0 as posible.
