[GNC] How to create a new Invoice report template

[Stein Erik Berget]

Hi all.
I've been wondering how I can create a new invoice report for suppliers.
The report is not to be created on paper, but to be delivered as email. The
format is in XML and is known to be EHF - Elektronic Trade Format.
https://anskaffelser.dev/postaward/g3/spec/current/billing-3.0/norway/
shows how this would look like. The advantage in this format is direct
handling of it, both at the supplier and you.

How do I start with this? Where do I create the hooks and the driver to
populate the report?
