Published "module" in package.json should point to sources that are transpiled to ES5, except import statements

[kayneb]

As per https://github.com/rollup/rollup/wiki/pkg.module, the module field should point to JS that maintains its import/export statements, but is transpiled to ES5 otherwise. Otherwise, any consumers that are using the module field in their build tools (like rollup or webpack when tree-shaking is enabled) must also transpile this dependency.

Generally, all libraries transpile down to ES5, except the module imports so as to not burden consumers.
