[JF][FXE] Replicate a raw dataset for legacy analysis code

Description

FXE has complained that a recent change in https://git.xfel.eu/detectors/pycalibration/-/merge_requests/735 broke their analysis code due to no longer copying over unchanged datasets, in this case data.trainId. Their code is using this JF-specific key instead of INDEX to align data.

Independent of the discussion on Zulip whether to treat these datasets differently, we should hotfix it for this week to not break their analysis code during operations.

How Has This Been Tested?

I guess, based on our discussion last Friday. We will need to further the life span of this change.

So I assume we need to merge this to master for further releases.

Yes, agree.

I rebased the MR on top of master, the earlier merge of using the DataFile API caused a conflict.
