Review comment (suggestion):
Since the access token is mandatory we might as well make this fatal
```suggestion
        access_token = self._download_json(
            'https://api-rtva.interactvty.com/jwt/token/', video_id,
            headers={'Content-Type': 'application/json'},
            data=json.dumps({
                'username': 'canalsur_demo',
                'password': 'dsUBXUcI',
            }).encode())['access']
```
