[com8]: Issue with PSC Layer containing only zeros at AIMEC analysis and contourplots

[RolandFischbacher]

com8MoTPSA sometimes produces an empty PSC layer (containing 0 at each pixel) with specific inputparameter combinations. The postprocessing with AIMEC and out3Plot.plotContours (in runAna4ProbAnaCom8MoTPSA.py) does not not work with raster data that is 0.
