In ESM projects, where napi bindings are just one part of the repo, mixing ESM and CJS files can be a huge pain.
It would be nice for napi-rs to generate an index.js that is valid ESM.

At a bare minimum, this can be done by adding the following lines to the top of the generated file:

import { createRequire } from 'node:module';
const require = createRequire(import.meta.url);

const __dirname = new URL('.', import.meta.url).pathname;

and updating the exports.
