        public static CompletableFuture<Resource> findResource​(RDFConnection rdfConnection,
                                                       IRI identifier,

                                                       boolean includeLdpType)
        Try to load a Trellis resource.
        Parameters:
        rdfConnection - the triplestore connector
        identifier - the identifier
        extensions - a map of extensions
        includeLdpType - whether to include the LDP type in the body of the RDF
        Returns:
        a new completion stage with a Resource, if one exists
        Implementation Requirements:
        This method will load a Resource, initializing the object with all resource metadata used with getModified(), getInteractionModel() and other data fetched by the accessors. The resource content is fetched on demand via the stream() method.
