Release with types

[Benjamin Minixhofer]

Hi. Thanks for this library!

Would it be possible to do a patch release including the types from 7a367d2?

I want to use web-worker with Typescript but I noticed that this fix was done on Apr 25th while the latest release v1.0.0 was done on Apr 17th so it doesn't include types.

FYI: PR #18 is required to get typings to work.

EDIT: It's merged 👍
