feat: support dual package

[azu]

This is example migration step for tsconfig-to-dual-package

1. Install tsconfig-to-dual-package && add type and exports
2. Update tsconfig.json for ESM and Add tsconfig.cjs.json for CJS
3. Use --loader ts-node/esm instead --require ts-node/register
4. Convert source code to ESM

npm run clean
npm run build
npx publint
# tsconfig-to-dual-package-example lint results:
# All good!
