• Added verification_status choice field (as per: https://www.hl7.org/fhir/valueset-condition-ver-status.html)

• Updated discharge summary to reflect the same.
• Added support for annotations in patient CSV export
• Updated Patient CSV export to reflect new consultation diagnosis, dedicated column for each verification status + principal
• Renamed PatientRelatedPermissionMixin to ConsultationRelatedPermissionMixin (see comment for details)

Additional changes:

PatientRelatedPermissionMixin has been renamed to ConsultationRelatedPermissionMixin as the mixin checks upon the fields self.patient and self.assigned_to which are specific to the consultation model and not the patient model.

It never failed so far in other places because:

1. It was only inherited by the PatientNotes model and the Consultation model itself.
2. It never failed so far for PatientNotes as we were not performing edit/object read with it (only create and list which was not dependent didn't have a check on assigned_to).

So the mixin has been renamed to: ConsultationRelatedPermissionMixin and a method has been added: get_related_consultation which defaults to return self.consultation and has been overridden in the ConsultationModel to return self.
