Description

Rust allows you to choose a start function other than "main", however by default "main" is the start function. There is code prior to invoking the start function to determine what it is. Often this is uninteresting to us, so it would be good to add a flag to optionally remove it from the graph.

Contributor guide

Research direction
Add a command line flag to optionally skip the `lang start` component in the graph generation. You need to modify the graph generation code to check for this flag and skip the start function block if set. Look at how the start function is currently resolved and inserted into the graph. Ensure the flag is documented and tested.
