Feature request: DOT (or similar) graph generation from WDL

I’m not sure if this falls under the umbrella of things miniwdl does, but it would be nice if it could generate a graph file (using DOT or some similar format) from an input WDL. This feature was supported by cromwell’s womtool graph command but it has never worked for WDL 1.0. I’m sure miniwdl has all the data needed to generate such a graph, and someone could use it as a library to do this as well.

Consolidated from #322

We have a codelab on using the AST to create a crude graphviz visualization, https://miniwdl.readthedocs.io/en/latest/wdlviz.html and a slightly (not much) better version checked in the repo: https://github.com/chanzuckerberg/miniwdl/blob/master/examples/wdlviz.py We probably won’t have bandwidth to fully flesh this out in the near future, but would definitely welcome if someone else is able to run with it!

imho graphviz is just too dated for this.
