single arity deprecation warning for Rails 6.1

[nicksoto]

DEPRECATION WARNING: Single arity template handlers are deprecated. Template handlers must
now accept two parameters, the view object and the source for the view object.
Change:
  >> RablRails::Handlers::Rabl.call(template)
To:
  >> RablRails::Handlers::Rabl.call(template, source)

A potential change here would be:

module RablRails
  module Handlers
    class Rabl
      def self.call(template, source=nil)
        %{
          RablRails::Library.instance.
            get_rendered_template(#{(source || template.source).inspect}, self, local_assigns)
        }
      end
    end
  end
end

It will be amazing if you may merge it into master 👍
