simplify passing annotation data through OSRM pipeline using the node-based datastore

- separates node-based graph creation and compression from edge-based graph creation
 - moves usage of edge-based node data-container to pre-processing as well, unifying access to node-based data
 - single struct instead of separate vectors for annotation data in engine (single place of modification)
