Consider unicode line characters to visualize the tree

This package has a nice way of displaying the tree that I think could be easier to follow than the current way pipdeptree works using ├── style characters:

Unicode tree characters are very cool, i use it personally everywhere i need, however johnnydep does not perform it itself, it stands on https://pypi.org/project/anytree/
