title: How do I set slug limit using friendly_id gem?
body: <p>I'm using friendly_id (4.0.10.1) and this is my class:</p>
  
  <pre><code>class Article &lt; ActiveRecord::Base
  
    extend FriendlyId
    friendly_id :name, use: [:slugged, :history]
  
  end
  </code></pre>
  
  <p>How do I set a 49 characters limit for the slug field? The Gem works fine, it's just that I need to set this 49 limit managed by the gem and not by adding an extra step on the code.</p>
