Bump pandoc-types #4
Description
Before I found this GitHub repo, I shot a message to @Warbo via email with a patch that bumped pandoc-types. That commit is colindean/panpipe@2ef9161 on my hard fork of this repo. Unfortunately, GitHub won't let me do a PR from that repo to this one. The change is trivial so I'm skipping the multi-step process of deleting my fork and recreating it as a GitHub fork.
