Twitter oEmbed has changed

[triplingual]

The oEmbed API endpoint for embedding tweets has changed.
In (VCO.Media.Twitter.js)[https://github.com/NUKnightLab/StoryMapJS/blob/master/source/js/media/types/VCO.Media.Twitter.js] line 31, the code reads
api_url = "https://api.twitter.com/1/statuses/oembed.json?id=" + this.media_id + "&omit_script=true&include_entities=true&callback=?";
Now the pattern would be api_url = https://publish.twitter.com/oembed?url=" + this.media.id, e.g. https://publish.twitter.com/oembed?url=https://twitter.com/Interior/status/463440424141459456

I haven't looked to see what the difference is in the returned JSON, hence why I'm filing as an issue rather than forking and creating a PR.
