tauRec: add flags for calibration files
Hello,
This MR is adding tauRecFlags for the calibration files of the main tau algorithms, so that they can be changed on the fly with a preExec. It will be very useful for the upcoming R22 tuning campaign, in case we need to rerun reconstruction with updated tunes. A couple of deprecated flags were dropped. This MR does not change the reconstruction output.
Cheers, Bertrand
