v2.0.2 - Actually support ESM and CJS

Release notes

v2.0.1 attempted to support ESM and CJS, but it instead changed the module support from CJS to ESM which is a potentially breaking change based on the user's JS runtime specification. This change fixes the package.json file to support ESM or CJS, depending on what's required by the user's runtime.

What's Changed

• add support for both esm and cjs by @charkour in #145
