Publish v0.5.0 to NPM

[chadfawcett]

Hey there! Dropping the dependencies in #71 was a great improvement. Looks like you tagged v0.5.0 on GitHub, but npm's most recent publish is v0.4.4 from 3 years ago.

Could you publish v0.5.0 to npm?

Aside, the package seems to be in a fairly stable state and used by a lot of people. Would it be worthwhile bumping to a stable v1?

Second this! Looks like v0.5.0 has been forgotten

Hey, thanks for the reminder everyone. My apologies on the timing on this. Just published 0.5.1.
