[PWGCF] Lambda cascade correlation

[Oveissheibani]

Lambda-Cascade correlation refactors:

Old: LambdaTableProducer + CascadeSelector + LambdaR2Correlation + CascadeCorrelations
New: LambdaCascadeProducer + LambdaXiCorrelation (LambdaTracksExtProducer kept)

Added:

• Combined Lambda + Cascade producer -> single event loop
• IsTrueCascade column -> MC truth filter
• processMCGenXi / processMCGenOmega -> gen-level R2 closure
• Eff/Gen + Eff/Reco maps -> 3D (cent x pt x y) efficiency
• OutputObj -> per-candidate topology + truth tags
• EventCuts struct -> centralized event selection
• ITS strangeness tracking switches
• processAllPairs, processYields

Removed:

• CascadeSelector, CascadeCorrelations

Main Advantage:
One event loop -> Lambda and cascade share identical event sample

I apologize. I rechecked the standards agains but it failed again on O2 linter again. I need a day or two to fix it.
shall i close and reopen again or keep this one ?

No need to close the PR. You can keep it as draft until you are done with the fixes. Please note that you can enable automatic local formatting and run O2 linter locally as well. See the documentation.

@Oveissheibani Why are you trying to disable the O2 linter errors?

@Oveissheibani Why are you trying to disable the O2 linter errors?

I ran
python3 Scripts/o2_linter.py PWGCF/TwoParticleCorrelations/Tasks/Lambdacascadecorrelation.cxx
O2 linter result: Issues have been found.
Exceptionally, you can disable a test for a line by adding a comment with "o2-linter: disable=" followed by the name of the test and parentheses with a reason for the exception.
To tolerate certain issues in a directory, add a line with the test name in "o2linter_config".
So I tried to rename the file and the structs inside so this test can pass.

1. Sure. Apology again. Fixed the comment and removed the distorted log.
2. I realized my original O2 linter was pointing to the mismatch of struct names and the filename. I changed the whole name of the files (Lambdacascade->LambdaCascade), but again the CMAKELIST gave me an error for the name of the task that does not belong to me( r2p24id / lambdacorr / nuclei-balance;). Then I returned the names to normal to avoid CMAKELIST file to be compared. The reason I added that line was a mistake to avoid the failing (wrong strategy).

I am currently working to resolved my confusion since I don't have that much experience in GitHub. Sorry if you get ping anytime it fails, and thanks for your patience.
