Detect probe orientation automatically when an asymmetric wire pattern is used

[Sunderlandkyl]

fCal_1.0_Wiring_1.0 is symmetric, therefore there is no way to tell if the probe is rotated 180deg. fCal_1.2_Wiring_1.1 has an asymmetric wire pattern, so it should be possible to determine the wire labels automatically, regardless of the orientation of the probe. However, it should be tested that the labeling really works correctly for any probe orientation. Once the display of the wire names in the segmentation dialog box is completed (#308) then this functionality can be tested easily. If the labeling is correct only for a certain probe orientation then the labeling algorithm shall be improved so that it works for all probe orientations.

I remember assuming that any probe orientation would work because the pattern was asymmetrical, leading, of course, to trouble and hair pulling 😄
