Documentation issue: usage with TypeScript is wrong

The "[TypeScript Usage](https://www.npmjs.com/package/jimp/v/0.16.13#typescript-usage)" section on NPM says that the package needs to be imported as default import:

```ts
import Jimp from "jimp";
```

But it's incorrect. The correct import is a named import like this:

```ts
import { Jimp } from "jimp";
```

Your website docs is correct but the README on NPM is wrong.
