Add predicted text and confidence associated

Depends #36 (closed)

We need to add the associated text and confidence for each detected object.

To do so we need to add the confidences as argument of plot_attention and get_predicted_polygons as we need the confidence scores in get_polygon.

We can add two keys to the dictionary describing the object:

• text,
• text_confidence: the average of the confidence scores on the contour.
