Support for ESM. Modules are not concatenated

Is your feature request related to a problem? Please describe.

The wrapper ESM approach doesn't produce the most optimal bundles.

Describe the solution you'd like

It'd be better, if this pkg was built using rollup for the most efficient builds for every environment.

• shipped with built-in TypeScript & written using latest ES

Additional context

In the following example, uuid is "annoyingly" a single module that is not concatenated by webpack.

How exactly are you building your bundle? This package is built in a way that webpack and rollup should pick up optimized ESM builds that allow for tree-shaking.

Could you provide a minimal reproducible example for how you got to the bundle shown above?

Also the module is written in ESModule syntax for precisely the reasons of tree-shakeability and we don't include the TypeScript types on purpose, see #368 (comment).

oups, I apologize, it was improper dependencies hoisting, that uuid on the graph above is 3.4.0
