[IMP] l10n_ar_ux: add qr-code for invoice payments

Add a new field in the journals to fill with a string that will be used
to generate a QR-code that will be printed in the invoices report.
Also, it adds the possibility of defining a label to be shown before
the qr in the report to give to the final user more information.
