[IMP] POS: allows to create invoices for a pos order at a later time

Some countries, such as mexico, require a seller to be able to
generate an invoices from a ticket from a sale done in a shop,
even after a few days.
This change aims to allow this, by allowing to create an invoice at
a later date after the POS has been closed.
This is done by partially reversing the POS closing entry, and then
generating an invoice the same way it would be done at the POS closing.

The customer can scan a QR code if enabled in order to request the
invoice by himself, requiring him to fill a for to give the customer
information required for the invoicing.

Allows to fill additional fields dependent on the localization that are
required to be set on the partner or the invoice.
