Add JUNGFRAU roi-definitions to update_config.py script

Description

Yohei has asked if the JUNGFRAU ROIs can be set out of office hours. So far we've just done it by editing config files directly. This adds it to the script so we can tell him how to do it.

How Has This Been Tested?

Running the script without --apply, so the changes aren't actually made:

python3 update_config.py --karabo-id FXE_XAD_JF1M --proposal 5686 --correct --roi-definitions 2 110 165 0 1024 -2

Types of changes

• New feature (non-breaking change which adds functionality)
