Check if `detectors_file_updated` can be written at the beginning
I just got this error message due to a missing folder:
|14:20:44.995| (FATAL) Error during execution of run:
Cannot create detectors file /home/lachnit/dSiPM_TB2/run_ana/geo/mimosa_dsipm_dut_aligned.geo
Please check your configuration and modules! Cannot continue...
Unlucky part: this happened after the alignment. While the shift is still shown, this check should probably happen at the beginning, not at the end.
