Etesian should use the CellGauge slice step when adding the feed cells. 

* Bug: In EtesianEngine, it was using the vertical track pitch from the
    routing gauge, but it may differ from the cell pitch. For example in
    "cmos350" the cell step is 10 lambdas while the vertical routing
    pitch may be only 8 lambdas.
      This bug shows because now we try to use the non-PinOnly routing
    gauge for the reference routing gauge.
