PSX_Operation: Backdown filtering order

A common tweaking algorithm done by users is to find the lowest filter
order which has the data from all combinations passing. As that is
manually quite tedious we now do that for her.

The idea is to start at some maximum order and then get he realized order
for each combination. If the realized order is constant for all
combinations, we are done. Otherwise we try the minimum order again and
should then be finished.

This is done for both sweep and deconv.
