@AWinterman ... Hi Andrew... Not sure if you wanted to review first before making a release... This adds TypeScript as well as modernizes to use ES modules. It's technically a breaking change as it adds an exports field, but I don't think that should affect any of the users.

Do you think you'll have time to review? Otherwise, I can make a fork... Wanted to also add a sync version. Thanks!
