Prepare the code to the the TCDS information

[venturia]

TCDS is recording both the history of the previous L1As and the orbit number when the B-GO signals have been issued for the last time. The code in DPGAnalysis/SiStripTools have to be modified to use these new data formats (still to be defined) and ad hoc code to compare SCAL and TCDS on large statistics have to be written
