NVR with realtime local object detection for IP cameras

* Save initial frame of new objects to frame cache Objects that move quickly through the frame and are only seen briefly may not have the update() method called to save thumbnail_data, and may not have the initial frame saved to the tracked object frame cache. This caused a "Frame missing from frame cache" message that was patched by #7313 but this sometimes caused the wrong frame to be chosen for the thumb/snapshot. * Tracking tweaks - When registering new objects, use the past detections from Norfair to populate self.positions and self.stationary_box_history. This prevents the first call of update_position() from triggering a +1 on the object's stationary count (because the iou would be 1.0). - Add a specific tracker for dedicated LPR cam license_plate objects using a lower R value and higher distance threshold to account for fast moving plates. - Add helpful debug messages and keep them disabled with `if False:` |

Frigate - NVR With Realtime Object Detection for IP Cameras
English
A complete and local NVR designed for Home Assistant with AI object detection. Uses OpenCV and Tensorflow to perform realtime object detection locally for IP cameras.
Use of a GPU or AI accelerator such as a Google Coral or Hailo is highly recommended. AI accelerators will outperform even the best CPUs with very little overhead.
- Tight integration with Home Assistant via a custom component
- Designed to minimize resource use and maximize performance by only looking for objects when and where it is necessary
- Leverages multiprocessing heavily with an emphasis on realtime over processing every frame
- Uses a very low overhead motion detection to determine where to run object detection
- Object detection with TensorFlow runs in separate processes for maximum FPS
- Communicates over MQTT for easy integration into other systems
- Records video with retention settings based on detected objects
- 24/7 recording
- Re-streaming via RTSP to reduce the number of connections to your camera
- WebRTC & MSE support for low-latency live view
