How to use it with typescript for type safety?

How can I use this package with type safety? Is there any way to extend JsonScehamType to includes the types for ajv-format? I couldn't find a way to do that.

```
import { JSONSchemaType } from 'ajv';

type Example = {
age: number;
name: string;
};
const sample: JSONSchemaType = {
type: 'object',
properties: {
age: { type: ['integer'] },
name: {type: ['string'], format: ['']}
},
};

```
In the above example I want to apply some formats to `name` but it's type is `string`.

thanks.
