Bugfix saving images

Fixes an issue where images were saved regardless of target detection. Also adds a processed image with a constant filename to make it easy to display on the front end

Adds saving image with bounding box for object detection

Adds event image_processing.file_saved and saving of images with bounding boxes if save_file_folder is configured. An example automation is provided in the readme to send a notification with the saved image.

Adds image_processing.object_detected event

This release adds an event image_processing.object_detected which is fired for each object detected.
The event payload includes:

• classifier : the classifier (i.e. deepstack_object)
• entity_id : the entity id responsible for the event
• object : the object detected
• confidence : the confidence in detection in the range 0 - 1 where 1 is 100% confidence.

An example automation is provided in the instructions showing how a notification can be sent when a person is detected
