* Capture nest still images from events
Use python google-nest-sdm API for fetching images. Update home assistant
to use the google-nest-sdm API for fetching the image contents generated
by the server. This uses the existing websession object for server fetches,
reducing the amount of new code and facilites unit testing using the existing
mechanism.
Simplify tests using the image fetch API rather than a snapshot API
