Fixes for some scans
I have a few suggested fixes for the scans -- if I am wrong on this please let me know!
- Lin FE pixel threshold tuning should have min TDAC = 0, not -15
- Lin FE pixel threshold retune scan should use GlobalPulseRt 16384 (same as other scans)
- LatencyConfig in sync analog scan should match delay, otherwise no hits are seen
- In Rd53aGlobalFeedback.cpp, when m_pixelReg was not initialized, it was somehow flipping the 1 switch instead of the default (at least when I tried running last week). Setting this to 0 by default avoids this problem.
