Relabel node/edge_ids when node_id start at 0 (crashes motile_tracker)

[TeunHuijben]

Closes #248

motile_tracker has the problem that the segmentation looks weird when the graph/geff has node_ids starting at 0

This PR add a funtracks function that, upon graph building, relabels the node_ids (and accompanying edge_ids) to start at 1 (all +1)
