For `stock`, adds package type demo data (pallet and box).
For `barcodes_gs1_nomenclature`, adds a custom rule (AI 91) to recognize
the package type in the Barcode Application.
As there is no standard GS1 nomenclature's rule for the package as
defined by Odoo and there is a bunch of free-to-use AI (from 91 to 99),
using one of them for the package type could be useful to be able to
scan a new package and create it on the fly with the wanted type.
