Label edges of trajectory

[kverstae]

Labeling of the edges could help make the trajectory more interpretable. By adding the edge labels to the dimred plot and the heatmap, it would become easier to link information of both plots to each other, especially in more complex trees.

Good point, we'll add this once we work further on the labelling part of the trajectory :slightly_smiling_face:
