init CLI command

[HeavenVolkoff]

init CLI command with which a new project can be created instead.

The init command then ask:

• Gjs or node-gtk
• CJS or ESM

To keep the command from getting too complex we should concentrate on the most important for now, if there is a need for more configuration options we can always introduce them, so e.g. I would make esbuild to the default bundler and not ask for another.

The init command then does the following:

• Runs npm init
• Parses the created package.json (in this way we also have the information that was entered)
• Rebuilds the package.json by
  • Adding some default scripts to the package.json (like build:types, build:app, ..)
  • Adding esbuild to the devDependencies
  • Adding ts-for-gir to the devDependencies (as soon as I have create a new npm package (I think I will name it @ts-for-gir/cli))
• Creates a tsconfig.json (with your suggestion to exclude the DOM types)
• Creates a esbuild.js
• Creates a .ts-for-girrc.js with the chosen
  • environments: "gjs" | "node"
  • moduleType: "esm" | "commonjs"
• Creates a src/index.ts as the starting point with a simple example
