Update renderkid to 2.0.7 and release?

Hi! I need to address some vulnerabilities including one for `css-what` https://www.npmjs.com/advisories/1754 which is a dependency for `renderkid` and fixed in `renderkid 2.0.7`

Would it be possible to update `renderkid` from `2.0.7-dev.1` (if it is in fact needed?) and also to release a new version of `pretty-error` (seems needed regardless as the latest has `renderkid 2.0.6`)?

If helpful for me to do a PR that bumps renderkid, please let me know 😄 I wanted to check in with you first!

Start with the renderkid entry in package.json and verify how the current development and published versions relate to css-what advisory 1754. Done means deciding whether renderkid should be updated and determining whether a new pretty-error release is needed.
