Allow access to notification thumbnails

Is your feature request related to a problem? Please describe.
Not a problem but something that would be nice ... today, I can either take a snapshot or download a video (I'm using Home Assistant). I have noticed in the last few days that my iOS Blink application has started including a still image in the notification about motion detection and this image is reliably showing a frame that contains motion. I guess that Blink is doing magic in the cloud to find a useful video frame to show in the notification.

Describe the solution you'd like
At the very least, the ability to access the latest notification thumbnail for each camera. Better, a list of all thumbnails if such a list exists (I assume it's per video captured as the notifications persist and I can look at each one independently from my Lock Screen).

Additional context
I would like the option to ripple this through in to Home Assistant somehow. Perhaps the camera entity could show the most recent notification thumbnail instead of the last snapshot. Perhaps the ability to download all of the thumbnails along with the videos.

This would be a good add, just need to uncover the right API endpoint.
