bump admc/wd to use 0.2.0

admc/wd was [bumped to 0.2.0](https://github.com/admc/wd/commit/5d00123d416604b12e10a712613825f9a9e9d652) so it would be good to update that dependency before the next tag of intern if possible.  i'm catching up on the repos i follow after being out of touch for a while so if i get some time i'll open a PR but just wanted to open this issue now to make sure it didn't get looked over in the next intern release.
