Change Tags so i can filter in Darktable after filmtype

Some tags had the wrong tagname and where therefore not included by exiftool

For exiftool to merge exifdata from the jsonfile with a corresponding
image, the filename must be statet in the json as a field "SourceFile"

This change will automaticly scan the provided directory for .tif files
and extracts the shotnumber from the filename. This shotnumber is then
used as a key to merge the filename into the provided metadata from the
logbook json

These images are as they came out of vuescan.
I sized them down with Imagemagick
```
magick.exe mogrify -format tif -resize 1% *.tif
```

json was created via Logbookapp: Export->json

before only converted metadata made it to the resulting list.
Now i remove the objects which need to be converted from the original
list and merge the converted and original list together.
