Updates of Herschel analysis code for delay scans

Improve Herschel analysis code to:

• allow faster handling of delay scans in HCDelayScan.{cpp,h}
• allow tupling of L0 response (in HCDigitTuple) as well as a few bug-fixes that made analysis of delay scans using tupling complicated (bxids for TAE +/- 1 were offset by 49 (=int('1'), interestingly) instead of 1)
• first commit of script that allows analysis of delay scan output using tuples
