Asciigraf should report the length of each branch

[AnjoMan]

Currently, asciigraf returns a networkx graph datastructure where every node has a position relative to the top-left corner of the string in which the network is drawn. It would be great if the graph also came with a length on each edge which indicated the number of characters in the edge. For example:

asciigraf.graph_from_ascii("""
            (13)           (10)
        n0-------------n1----------n2
                       |
                       |  (3)
                       |
                       n4
""").nodes(data=True)
>>> [('n0', {'position': Point(3, 8)}),
        ('n1', {'position': Point(3, 23)}),
        ('n2', {'position': Point(3, 35)}),
        ('n4', {'position': Point(7, 24)})]

If we did this, you could do something like

asciigraf.graph_from_ascii("""
            (13)           (10)
        n0-------------n1----------n2
                       |
                       |  (3)
                       |
                       n4
""").edges(data=True)
>>> [('n0', 'n1', {'length': 13}),
        ('n1', 'n2', {'length': 10}),
        ('n1', 'n4', {'length': 3})]

What about defaulting the length to the number of characters long the line is?

[AnjoMan]

@greatestape yeah that is what I was thinking would be a good behaviour
