A new Invoice Endpoint has been added. This allows optician data providers to send their invoices, using their own types of treatments
Invoices now have a invoice_type_id indicating whether they're a "default" invoice or an optician's invoice.
This change is backwards compatible
This version is backwards compatible with v1.1.1, meaning if you target v1.1.1 you can access both the old and new endpoints.
No changes are required to use v1.2.0 (or v1.1.1) if you only use the /invoices endpoint.
