corrected positions of volumes in RB24 after recent Cave updates

[amorsch]

Corrected positions of volumes in caveRB24 after recent updates to accommodate FOCAL in the barrel volume.
Since the mother volume has been shortened by 150 cm in the z-direction, the volumes have to be moved 75 cm closer to the center. This concerns ZEM , Compensator magnet and FDD (A-side).

For other reviewers, there's a little gear icon above the file diffs, with which you can hide whitespaces (the mentioned clang changes). @sahilupadhyaya92, could you run your simulation studies again with this branch to cross-check the location of FDD? Sometimes with the geometries, it's difficult to be sure what will happen just by checking the code.

[sawenzel]

@amorsch : This PR had considerable whitespace changes. Would it be possible to make a version with just the necessary bug-fix changes? (I am puzzled why clang format applies global formatting changes. We typically only make sure that each new diff is well formatted in order to stay as local with the code changes as possible: (git clang-format HEAD^).

[amorsch]

@sawenzel Ok I will remove the style changes. I thought it will in this case not pass the corresponding checks.
@andreasmolander Displaying the geometry with root I see the FDD now centered at z = 1695 cm

[shahor02]

@amorsch does this PR modify the geometry/materials in the acceptance range (i.e. do we need to regenerate CCDB geometries and material LUT)?

@shahor02 No, only elements in the very forward direction have been moved.

[sahilupadhyaya92]

@andreasmolander @amorsch
I have checked and everything looks ok.

[andreasmolander]

FIT code changes OK by me (@sahilupadhyaya92 also cross-checked the location). Not sure if I have a say regarding the other changes so I maybe leave final PR approval to @sawenzel or @shahor02
