Sub-Makefile Support

[tommy-u]

Hi, I think this tool is fun and awesome for visualizing projects.
Are you interested in PRs for adding sub-makefile (recursive make invocation) support? It looks like make -Bnd provides all the output needed for this. From your experience, do you think there's something that makes this much harder, or was it just outside your use case?

@tommy-u Hi, last time I've checked, the output was too complicated to be parsed. Fee free to try :-)
