feat(cli): add automatic project creation

[Thomsr]

This pull request adds a new package: cli. This package contains all the command line interfaces that Motion Canvas has.

With this pull request comes the ability to type mc into your terminal and get prompted with several options which consist of the following:

mc
├── add
     ├── scene
     ├── project
     ├── component

This allows the user to create a new scene, project or component with ease.

Closes: #301

My current testing setup is as follows:

test/
└──src/
     ├── scenes/
     └── vite.config.ts

And then call node ..\packages\cli\index.js from inside the test/ directory

I am open to any feedback you might have, please dont hesitate.

I think we should use typescript here.
The create package is kept extremely simple with as little overhead as possible because it needs to be snappy - it's downloaded on demand when npm init is used.
Here, the package will be actually installed globally by the user, so we can have more freedom.

I will add the component command later, I think that just scene and project will suffice for now.
