Typescript errors with captureFetchGlobal

When importing the `captureFetchGlobal`:

```ts
import { captureFetchGlobal } from "aws-xray-sdk-fetch";
const myFetch = captureFetchGlobal();
```

This triggers eslint errors:
```
Unsafe assignment of an `any` value.
```

And then when calling it:
```
Unsafe return of an `any` typed value.
Unsafe call of an `any` typed value.
```

Is there any way around this?
