Missing castings

[hugoattal]

Describe the feature

Hey 🙂!

So I'd like to parse any code using builder.raw, but it fails on some castings.
For example, I'd like to generate foo(bar) (bar being a variable), doing it like this does not work:

builders.functionCall("foo", builders.raw("bar"));

Here are a few more examples.

const result = builders.raw("bar()");
console.log(generateCode(result)); // works

const result = builders.raw("bar"); // MagicastError: Casting "Identifier" is not supported
console.log(generateCode(result));

const result = builders.raw("() => 'a'"); // MagicastError: Casting "ArrowFunctionExpression" is not supported
console.log(generateCode(result));

I can help with the implementation if needed!
