title: Get a Discord Role by Id
body: <p>I'm making a Discord bot but just ran into a problem.</p>
  
  <p>I want to modify a role. A specific role. I know how to do that with <code>edit_role</code>, but I need to get the Role object to edit it. Now, that's the problem.</p>
  
  <p>How do I <em>get a Role object by the role's id</em>? Or can I <em>use the id in the Role argument</em>?</p>
