feat(ts/fast-strip): Distinguish invalid vs unsupported

[kdy1]

Description:

I tried adding a property to the error thrown, but wasm_bindgen does not support adding property to an error nor creating different kinds of errors.

So I throw an object with code and message instead.

So when it has unsupported syntax it will have the label help: unsupported syntax.
That means I have to match with a regex which I think is not very efficient.
I'd rather not have the longer message, the error message is descriptive enough for users.
If its not possible to have it easily accessible in js I'd just remove the cause and leave it as is

@marco-ippolito Is it fine to throw an object? I think wasm_bindgen would allow creating object with arbitrary properties.

(Not sure if it supports throwing them, though)

I think so since we always wrap what is thrown into a Node error. Let's give it a try

@marco-ippolito Can you take a look on the new error output?

So I'd expect always an object with
code and message
Code could be either InvalidSyntax or UnsupportedSyntax
Message the usual error message

Yeap, I added some test cases

Thanks for adding the new tests.

My comments are non-blocking.

The ^^^ should point to the public keyword only.
