ITS alignment monitoring (check with QCv20240903), revised 20240919

[delico18]

New 14 plots(7, layer x 2, axis[z ~ alpide col, phi ~ alpide row] for ITS alignment monitoring are added.

• Circle Fitter (in XY plane)
• Line Fitter (in DZ plane), D is almost same as the path length of particle.

Based on Least Square Fit, we can observe the residual of particles' track, which we believe they will show the alignment quality of ITS.

I will apply the clang format at the end once all comments have been implemented

2024 09 19 update

There seems to be tiny errors in getting layer of cluster, and I corrected the lines.

Options...
to activate alignment monitoring(itsTrack.json) is added.
to request the minimum number of clusters / track for alignment monitoring(itsTrack.json) is added.

I updated the simple version of documentation that describes the fitting & residual calculation procedures.

Hello,

Nice new feature! General comments:

1. Size of new objects: I assume that TH2D is too much. Could you please check the size of objects in case of TH2D and TH2S/TH2I. I think that with such nice binning double is a quite overkill
2. Try to minimize influence of your code when AlignmentMonitoring set to FALSE: do not initialize objects/do not download geometry etc. Please, check that task still working if user will set monitoring to OFF.

Otherwise, looking forward to results of this new feature

The monitoring objects for residuals are now only activated when mAlignmentMonitor is true.
There is no more influence related to this object when this is set to false.

Please review this PR.(including TH2F vs TH2I)
