Feature Request: Field for property #246

I don't want to go all in with Java-like getters and setters. I want to treat my Dto's more like JSON objects thus I would like to define field in properties:

class Product
{
    /**
     * @Field()
     */
    public int $id;

    /**
     * @Field()
     */
    public string $name = "";
}

I know that this is anti-pattern in OOP, but I don't care, my API is mostly readonly and I use the classes as a type safer alternative for typical spaghetti mixed array code.

I also don't seem to find a way to do this myself without forking graphqlite. The MagicFields are for classes, Field is for methods, and if I implement FromSourceFieldsInterface I should have to make another external class (it's not usable on the e.g. Product above directly.)
