Title: Polygon should only be reviewed if disease extent class has changed since last generation

NB. Only commits on Sept 15 are relevant for this story (#213). Previous commits correspond to pull request for Story #219 (see here first https://github.com/SEEG-Oxford/ABRAID-MP/pull/189). I merged the branch in to prevent conflicts on GeoJsonDiseaseExtentFeatureProperties.
