This one is inspired from [PsySH's equivalent](https://github.com/bobthecow/psysh/blob/master/src/Psy/Presenter/MongoCursorPresenter.php).
Looking at the interface of the Mongo extension, the other classes may need a caster too.
So if a real Mongo user can write casters for them, that'd be great! (in an other PR, on top of this one)
