New for_collection method on Serializers that is pagination aware

[jwoertink]

This one may be stepping in a little too deep, but I have this overload method added in my app that helps me serialize a collection with pagination data added in. This helps with an API where the front-end handles the pagination.

def self.for_collection(collection : Enumerable, pages : Lucky::Paginator, *args, **named_args)
    {
      "items" => for_collection(collection, *args, **named_args),
      "pagination" => PaginationSerializer.new(pages),
    }
end

Then the PaginationSerializer is also generic enough to be added in by default

class PaginationSerializer < BaseSerializer
  def initialize(@pages : Lucky::Paginator)
  end

  def render
    {
      next_page:     @pages.path_to_next,
      previous_page: @pages.path_to_previous,
      total_items:   @pages.item_count,
      total_pages:   @pages.total,
    }
  end
end

It would be added in to this class
