Provide the package as an ESModule #189

Prerequisites

[X] I have written a descriptive issue title
[X] I have searched existing issues to ensure the feature has not already been requested

🚀 Feature Proposal

Currently the package cannot be used within an ESModule. When one tries to do so you get an error like

Motivation

Example
