and preparation for the edi module

This module now depends on l10n_latam_base
for the identification types and
l10n_latam_invoice_document for the invoice numbering.

It has its own implementation where you can choose
yourself the sequences you want to add on a journal in
a many2many.  By default, you will have the sequences
for the document types of the first journal. But you
can share them on other journals or create new sequences
for a journal.
