title: Get user banner in discord.js
body: <p>Is there any way to obtain user banner on discord using discord.js? User banner is new feature, so I am not sure if there is any way so far. I didn't find anything in docs. Eg. server banner is available on:</p>
  <p><code>https://cdn.discordapp.com/banners/GUILD_ID/GUILD_BANNER.png</code>.</p>
  <p>Something similar for user banner would be great.</p>
