siriwave: Module import does not work with Typescript

Hi @kopiro Thank you for creating an amazing library. I was trying to use it my Typescript application with import SiriWave from 'siriwave'; but I get Cannot find module 'siriwave ts(2307)'. literally with any compilerOptions.module variants in tsconfig.ts.

Typescript module resolution gives me the following:

======== Resolving module 'siriwave' from 'c:/Projects/tstest/app.ts'. ========
Explicitly specified module resolution kind: 'NodeJs'.

As a workaround I have added "main": "dist/siriwave.js" to package.json but I’m not sure that this is the way to go with rollup.js compilation. Meaning I do not know if rollup.js js generates package.json for you or not. Any suggestions on how to make the library usable in Typescript in the sane way?
