Retrieve image requires Jinja2 when getting images.get(image_id, include_embeddings=True)

When running in my local environment, jinja2 is not installed by default
```python
impresso_session.images.get(image_id, include_embeddings=True)
```
I got this error

```python
from pandas.io.formats.style import Styler 
AttributeError: The '.style' accessor requires jinja2
```

In my case, I had to install jinja2 to make it work
```bash
pip install jinja2
```
