changed f06 stress and strain format to match MSC

[victorkemp]

As well as changing the layout of stress and strain data, this removes the octahedral direct stress/strain values for each element because they're not in MSC's format. However, the max/min are still shown at the bottom. Octahedral max. shear values are still there for element center and each corner.
