Performance: Limit data layer state updates

[torkelo]

Various performance fixes

• [x] We were using infinity replay subjects so when coming back to a scene data layers emitted all their previous emitted results
• [x] Ignore replayed data layer results that has already been processed (this happens when a data provider get's re-activated, we subscribe the the SceneDataLayerSet this causes the ReplaySubject to emit last data, even if that has already been incorporating into the current state). Created a new DataLayersMerger that can detect when a result has already been seen.
• [x] In SceneQueryRunner ignore updating state when data layers are received if there are no annotations (And the previous result also had no annotations)
