Unable to use dynamic import() in cjs-files

Trying to use a dynamic `import()` statement will fail with: 
```log
TypeError [ERR_VM_DYNAMIC_IMPORT_CALLBACK_MISSING]: A dynamic import callback was not specified.
```
The error originates from an insufficient options object passed to the `new Script()`-constructor [node VM docs](https://nodejs.org/api/vm.html#vm_new_vm_script_code_options)
