Title: Function to get bytes for rendered graph PNG.

This adds a function to render the graph with GraphViz, as in the loom.io.view function, but returns the bytes for the rendered PNG rather than passing them to the default system viewer.

I've added this to support a loom renderer for Gorilla REPL. I'll send a separate pull request for that :-)
