Typescript Help: Client is not a constructor

I pulled the code directly from the typescript example in the README:

```
import * as ApiClient from 'kubernetes-client';

const Client = ApiClient.Client1_13;
const client = new Client({ version: '1.13' });
```

My only difference is loading the kubeconfig from the cluster:

```
const kubeconfig = new KubeConfig();
kubeconfig.loadFromCluster();
const backend = new Request({ kubeconfig });
return new ApiClient.Client1_13({ backend, version: '1.13' });
```

When I run this typescript gives me an error:

`Error initializing client: TypeError: Client is not a constructor`

I tried everything I could think of and searched the googles and couldn't come up with anything, any help would be greatly appreciated!

node: 16.15.0
typescript: 4.6.2

Start with the TypeScript example in the README and reproduce the `Client is not a constructor` error using the reported Node.js and TypeScript versions. Compare the README import and `Client1_13` construction with the `KubeConfig`, `Request`, and cluster-loading path shown in the issue. Done means the client initializes without this runtime error using the cluster kubeconfig.
