HCAL local reco improvement for drifting QPLL channels

[slava77]

see discussion in #20986
In Run-1 we had some channels that did not lock to the central BX timing properly

• M0 reco for these had a broader integration window
• M2, which defines the default definition of energy, by construction fits only to one pulse in a selected BX of interest, which can be wrong for these channels.

The idea is to capture the energy correctly for the drifting channels. Some options could be

• modify M2 to integrate OOT pulses for these channels
• return the "best of" M2 and M0 for these channels

From Dec 7 or so: there is one more PR that modified the behavior of reco in these channels #21651

@slava77 , has #23568 addressed/fixed this issue?

no, not really.
considering that this is only a Run-1 problem, this issue is slowly getting to a "will not fix" state

please comment if there is still a plan to do something special for these channels.
