feature request: add support for @author

It would be nice to add support for multiple @author entries.

Ideally @author would have this format:

```bash
@author Author Name <contact@email.com>
@author Other Author
```

And the resulting markdown would be something like :

```markdown
## Authors

- Author Name <[contact@email.com](mailto:contact@email.com)>
- Other Author

```

Thank you for your work.
