[sdw] Relax cardinality of hasUltimateFeatureOfInterest on ObservationCollection (#1163)

dr-shorthair has just created a new issue for https://github.com/w3c/sdw:

== Relax cardinality of hasUltimateFeatureOfInterest on ObservationCollection ==
(Arising from discussion in OGC/ISO 19156-rev EC)

Individual `Observation`s can have one or more `hasUltimateFeatureOfInterest`. 
Currently the cardinality on `ObservationCollection` is limited to one only, which is inconsistent.
