Updates required to the master branch to allow the pixel fast digitisation to run. Includes:
- Updates to the commonPixelFastDigitizationConfig() method in FastSiDigitizationConfig.py to ensure proper treatment and running ordering of PixelLorentzAngleTool methods.
- An update of the way SharedObject handles the its memory content for RectangleSegmentation::createSegmenationSurfaces() in Tracking/TrkDigitization/TrkDigEvent/RectangleSegmentation.cxx.
- The addition of clusters to fastPixelDigiOutputExpected() when the pixel digitization is on in Simulation/Digitization/python/DigiOutput.py.
These changes to not include any improvements to the SCT fast digitisation.
