/**
 * This plugin is designed to transform imports within Marko files to interop between ESM and CJS.
 * In Node, ESM files cannot reliably use named imports and default imports from CJS files.
 * Additionally, modules which are transpiled from ESM to CJS will use a `__esModule` property to
 * signal that the consuming ESM code should treat `exports.default` as the default import.
 * This plugin only modifies imports it determined to be for CJS modules
 *
 * Examples
 *   1. Source: ```import { bar as baz } from 'foo';```
 *      Becomes:```
 *        import _foo from 'foo';
 *        const { bar: baz } = _foo
 *      ```
 *
 *   2. Source:  ```import myFoo from 'foo';```
 *      Becomes: ```
 *        import * as _myFoo from 'foo';
 *        const myFoo = _myFoo?.__esModule ? _myFoo.default : _myFoo;
 *      ```
 *
 *   3. Source:  ```import foo, * as nsFoo from 'foo';```
 *      Becomes: ```
 *        import nsFoo from 'foo';
 *        const myFoo = nsFoo?.__esModule ? nsFoo.default : nsFoo
 *      ```
