[FR] Ability to override Frigate `latest.jpg` and `snapshot.jpg`

Continuing the discussion from #102 @hawkeye217 is looking for a way to override the latest.jpg and snapshot.jpg images rather than using the default ones from Frigate’s API.

Here is my proposed solution.

frigate:
  url: https://frigate.com:5000
  
  # defaults applied to all cameras and events
  attempts:
    # number of times double take will request a frigate latest.jpg for facial recognition
    latest: 10
    # number of times double take will request a frigate snapshot.jpg for facial recognition
    snapshot: 0
    # process frigate images from frigate/+/person/snapshot topics
    mqtt: true
    # add a delay expressed in seconds between each detection loop
    delay: 0

  image:
    # height of frigate image passed for facial recognition
    height: 500

  # override global frigate attempts and images per camera
  events:
    office:
      attempts:
        latest: 0
        snapshot: 5
        mqtt: false
        delay: 0

      image:
        height: 600
        snapshot: http://snapshot-url.com/image.jpg
        latest: http://latest-url.com/image.jpg

With this configuration the office camera has new values applied to it. I’ve disabled the latest processing by setting the attempts.latest to 0. The MQTT snapshot is also disabled by setting attempts.mqtt to false. You can also override the snapshot.jpg or latest.jpg image instead of using the ones provided from Frigate’s API.

You can also change the image.height per camera, but this will only apply to the standard latest.jpg and snapshot.jpg images from Frigate. In the above example because I have a custom value for latest and snapshot, then the height will be omitted.

@hawkeye217 I have all of these changes above ready locally. Just want to make sure the above makes sense before I release a new beta build with this. Let me know what you think!

Thanks for the fast turnaround! I’ll install it and test it today.
