Option for using 'T[]' instead of 'ResizeArray<T>'

[davedawkins]

I have a PR for this already.

The API I'm currently working with (Appwrite) has many declarations that use TS string [], and these should be mapped to string array (or string[]) in FS

Eg

declare class Api {
    account: {
        names: string[];
    };
}
export { Api };

Current output:

type [<AllowNullLiteral>] ApiAccount =
    abstract names: ResizeArray<string> with get, set

Preferred output:

    abstract names: string[] with get, set
