Generate syntax diagram

This could be done with a diagram generator such as:

• https://tabatkins.github.io/railroad-diagrams/
• https://www.bottlecaps.de/rr/ui

Or the rust railroad crate. See here for my new crate: https://crates.io/crates/pest_railroad_gen.

Would there be interest in a PR that integrates this directly into the Pest project/repo? I really don't want to maintain it and I think it would make a nice "out of the box" feature (as a separate lib/binary crate). Thoughts?

Awesome work! I'd need to look in detail whether it'd make sense for it to go to the main repo, but it looks like something that could definitely live under the pest-parser GH org.
I imagine it could be nice to integrate in the existing pest tooling, such as VSCode extension to have a command to generate it on a separate tab or if it could compile to WASM, perhaps there could be an option for it in the web fiddle editor.

Sounds good. I'm open to whatever makes sense, but yeah the VSCode extension would be great as a "preview" option or something on a grammar.
