Subject: [PATCH] [FIX] snailmail: mandatory cover page + handle cover page
generation
Pingen's v2 API does not offer an endpoint to generate a Cover Page automatically with an API call anymore, thus the need to generate it and append it to the invoice from the client-side beforehand.
Also make the Cover Page option mandatory due to the invoice being near
impossible to format for Pingen's validation needs. (Odoo 13 Only)
closes odoo/odoo#103385
