Backporting some changes made for CMS pixel high-rate testbeam

Adding new processors:
* EUTelConvertCMSPixel uses the CMSPixelDecoder to convert PSI46 raw data to LCIO
* CMSPixelClusterTupel writes out ntuples of clusters for outside processing (could be generalized probably)
* Minor changes to other processors, some bugfixes
this value should be large. for sensors with one size +-10 mm long, the size2-size1 will be convering +-20, the most extreme value we have now is +-20, so the minX and maxX are covering +-40.
