Basic npm scripts panel functionality

[FirstVertex]

I'm using this extension as a replacement for the built-in npm scripts panel. There are a couple of missing features that I believe would make a really nice addition to this extension.

1. Right click the package.json ("npm" node) and be able to choose "install". It runs npm i in the folder of the selected package.json
2. Right click the package.json ("npm" node) and be able to choose "open file". It opens the file in the VS Code editor.
3. Right click the package.json ("npm" node) and be able to choose "open in terminal". It opens a new terminal onto that file's folder.

Thank you for considering it.
