BE: MetNO: use intersection polygon in TAC
The intersection polygon is used if there are less than 7 coordinates in it. Add condition for norwegian FIRs (ENOR, ENOB) to this logic, use the intersection polygon if the coordinates are more than 0. No limit of 7 for these FIRs.
The logic is in the avi-messageconverter. This is the polygon logic in the knmi instance (which METno installs): https://gitlab.com/opengeoweb/avi-msgconverter/geoweb-knmi-avi-messageservices/-/blob/master/src/main/java/nl/knmi/geoweb/backend/product/sigmetairmet/SigmetAirmetUtils.java#L196
