Simplecast Support

[nathangathright]

As best I can tell, the only way we can add support for Simplecast URLs is to scrape the episode page for the href value of the Recast link. https://recast.simplecast.com/${episode_id}

With that episode ID, we can create an iframe with a src of https://player.simplecast.com/${episode_id}

There might be an alternate way to fetch the player URL from their sharable URLs with their API or oEmbed.
