Beta Release 0.4.0

This release touched almost every line of code. I am certain there are changes I have missed. I see much better bounding boxes and higher confidence scores for detections on my cameras.

Breaking Changes:

• Object configuration has changed again. Please reference the updated config example.
• Region specific settings are no longer available because objects can be detected outside the bounds of regions dynamically

Changes:

• By default, frigate only looks for the following object types: person, car, and truck. You must specify others if you want.
• Detected objects are now assigned an id and tracked across frames
• Regions are dynamically created for tracked objects
• If an object is against the edge of a region, a new region is dynamically created to ensure the entire object is included in the detection
• Dockerfile has been overhauled. Building should take less time and result in a smaller image size. There is still room for more improvement.
• Updated to the latest EdgeTPU libraries from Google
• Added a /debug/stats endpoint where you can see FPS for your cameras/Coral and various queue lengths
• Watchdog timeout for ffmpeg is now configurable
• Timestamp on snapshots is now configurable
• Support for UDP camera feeds

Docker image is available with docker pull blakeblackshear/frigate:0.4.0-beta
