PyJobTransforms: correctly read LHE files in trfArgClasses.py
PyJobTransforms: python3 fix: correctly read LHE files in trfArgClasses.py, so that the number of events (and weights) are calculated and submitted to metadata correctly.
For info: @mavogel @muschmid @dhirsch (Mustafa: can you, please, have a more general look at the file, possibly some other read statements need decoding too...)
