Add Filament by GTIN#596

I’m normally adding a batch amount of filaments; and since we have the GTIN from the filament database it could be nice to search and maybe batch create just by entering GTIN’s.

Currently using a physical barcode scanner; so (scope creep) - could be an option on the user to use the app barcode scanner or catch the text input (there are helper avascript snippet out there ;)
