Update xo to the latest version 🚀

[greenkeeper]

Version 0.18.0 of xo just got published.

Dependency	xo
Current Version	0.17.1
Type	devDependency

The version 0.18.0 is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of xo.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Update to this version instead 🚀

Release Notes

v0.23.0

Highlights

• In v0.22.0, we added support for .ts and .tsx extensions by default. This caused a lot of problems for non-TS projects, so it has been reverted pending a better solution.
