ConstStrict subset of fullTrafficIncidentCategories — every value here is also
a valid response category. The two values omitted ('animals-on-road' and
'narrow-lanes') are documented as response-only: the upstream's default-values
list is 0,1,2,3,4,5,6,7,8,9,10,11,14, intentionally excluding iconCategory 12
and 13. Including either makes the upstream reject the whole filter with
Unsupported categoryFilter parameter value.
Traffic incident categories accepted as
categoryFilterinputs by the Incident Details API.
