`options` parameter in serialize function is not supported by index et show function

[lohayon]

In the documentation, it seems to be an options parameter that be handled in the paginator

but the code does not handle it. It is never sent to the serializer. Please, see :+1: https://github.com/jeregrine/jsonapi/blob/master/lib/jsonapi/view.ex#L261

It is sent to the serializer if you pass the :options key to render("index.json", %{...}).
