Unarchived Data Fix

SwissFEL scan descriptions are JSON files containing references to absolut paths:

$ cat /sf/instrument/data/p12345/raw/run0123-ImportantData/meta/scan.json 
{
    "scan_files": [
        [
            "/sf/instrument/data/p12345/raw/run0123-ImportantData/data/acq0001.PVDATA.h5",
            "/sf/instrument/data/p12345/raw/run0123-ImportantData/data/acq0001.BSDATA.h5",
            "/sf/instrument/data/p12345/raw/run0123-ImportantData/data/acq0001.CAMERAS.h5"
        ],
...

Unarchived data arrives in /sf/instrument/data/p12345/work/retrieve/, and the paths in the JSON files need to be updated accordingly:

$ cat /sf/instrument/data/p12345/work/retrieve/sf/instrument/data/p12345/raw/run0123-ImportantData/meta/scan_mod.json 
{
    "scan_files": [
        [
            "/sf/instrument/data/p12345/work/retrieve/sf/instrument/data/p12345/raw/run0123-ImportantData/data/acq0001.PVDATA.h5",
            "/sf/instrument/data/p12345/work/retrieve/sf/instrument/data/p12345/raw/run0123-ImportantData/data/acq0001.BSDATA.h5",
            "/sf/instrument/data/p12345/work/retrieve/sf/instrument/data/p12345/raw/run0123-ImportantData/data/acq0001.CAMERAS.h5"
        ],
...
