Add Visual Studio Code extension

[dustinblackman]

Overview

VSCode extension would be a great addition, and likely where the tool would be used most.

Code actions example: https://github.com/microsoft/vscode-extension-samples/tree/main/code-actions-sample

Hi, do you have any update on this? That's something that would definitely be useful to me, and I'm sure to many others as well :)

My time is quite limited for side projects, and I don't use VSCode myself. Unfortunately I likely won't get to it anytime soon. :( I'm happy to accept PRs or reference other projects if anyone else were to take it on.
