transformation widget - rotate RSM
related to #96
in the transformation widget there is a “Rotate RSM” option which, when checked, should compensate for the 90 degree rotation given by the mounting of the basler camera at the beamline. This dataset doesn’t seem to exhibit that rotation for some reason (not sure if the detector was remounted or not), but I am unsure on whether the flip is the right way (maybe @Raquel Rodriguez Lamas can speak more on that if she has a test dataset).
