No default export warning in vscode

When writing:

```ts
import Worker from 'web-worker';
```

I similarly see: `No default export found in imported module "web-worker"` as a vscode warning

It's strange, because to me it looks like there is a default export:

```ts
type ConstructorOf = { new (...args: any[]): C }

declare const _default: ConstructorOf
export default _default
```
