 Utility to render the output of `fossa analyze -o` as a graph.
 
 This program isn't _guaranteed_ to not be broken by new FOSSA CLI releases,
 but we'll try to keep it from doing so especially since we try to keep output of FOSSA CLI stable.

+`rendergraph` is unlikely to get additional features; we'll almost definitely roll this into other tooling
+such as FOSSA CLI or `ficus` itself if we choose to make changes to how this works.
