[STALE] TracksData backend

[TeunHuijben]

• removing networkx completely from funtracks
• replacing the networkx graph backend with tracksdata
• use tracksdata.graph.SQLGraph for the tests

ToDos:

• get 100% coverage (on tracks.py and solution_tracks.py)
• replace IndexedRXGraph with SQLGraph in tests
• add masks/segmentation to SQLGraph
• replace tracks.segmentation with tracksdata.GraphArrayView (update .set_pixels)
• update to geff 0.6.0 (later)
