Package version 19.4.0 is broken (contains .ts files instead of .d.ts

I think 19.4.0 has a similar issue to what is described in #217, when it is installed i only see .ts files in the package, seems it is not built, 19.3.0 looks fine, that does have built js and .d.ts files

Sorry, these things happen if you have a manual deployment process. 19.4.1 has been released.

@michael-small I think we should think about an automated release process that supports multiple versions.
