Export es6 modules allowing this library to be shaken

Hello,

I am currently attempting to consume this package and I use es6 modules with Webpack tree shaking. However this package seems to only output commonjs. Are there plans to output es6 so that it can be shaken as needed? Or maybe I am missing something?

Review the package's current CommonJS output and build configuration, then check how its published entry points are consumed by Webpack. Done means the package provides an ES6 module output that Webpack can tree-shake, with the existing CommonJS consumption still accounted for.
