Title: Fix method resolution error in FaceAnalysisDisplay node

``Select Face`` node returns a ``ProtoGeometry.Surface`` which can't be converted to ``ElementFaceReference`` directly, so changing the type of parameter to ``object`` and then call ``ElementFaceReference.TryGetFaceReference()`` to do the conversion from ProtoGeometry to Revit element.
