Import compatibility with ES modules in 2025

Thanks for this library! I had some trouble using this with ES modules. So I wanted to share how I was able to import it and use it for others.

The default import object as it's currently implemented: `import extractDate from 'extract-date';`

Seems to have nested defaults:

```
[Object: null prototype] {
__esModule: true,
default: { default: [Function: _default] }
```

So my fix:
```
import * as ed from 'extract-date';
const extractDate = ed.default.default;
```
