ValueError: could not convert string to float: 'F'

Dot2tex version 2.11.3

This is a duplicate of #78, but that issue was closed without resolving the problem.

During handling of the above exception, another exception occurred:

    log.debug("Failed to parse drawstring %s\n%s", s, err.message)
AttributeError: 'ValueError' object has no attribute 'message'

The second exception should be resolved by using str(err) instead of err.message.

digraph G {
    rankdir=LR
    node [shape=box];
    graph [nodesep="0.5" padding="0" margin="0"];

    train -> cluster;
    cluster -> annotate;
    annotate -> cluster;
    annotate -> name;
    annotate -> train [constraint=false, style=dashed];
    
    cluster [label="Cluster"];
    # This line seems to be the problem. I suspect dot2tex chokes on the \n:
    annotate [label="Validate\nGrow"];
    train [label="Train", style=rounded];
    name [label="Name",style=rounded];
}

The key to rendering newlines in nodes is the align option:
The above line should be rendered as \draw (241.5bp,39.735bp) node [align=center] {Validate\\Grow};.

#83 fixed the second exception but not the first. It seems, however, that this fix did not yet make its way to PyPI.

EDIT: In the very last commit, this bug is fixed. Thanks!
