Add object filter ratio

Per issue #2948 (take two, this time targeting the correct branch release-0.11.0)

I was not able to figure out how to run frigate in a dev. container on a recorded video the way I wanted to for testing, but am open to doing so if I can get a bit of help/instruction.

I also did my best to maintain existing style/phrasing throughout, but feel free to make adjustments/requests if you think it should be improved.

Thanks!

Since you added a field to the model you will also need to add a migration class to the migrations folder. Should be able to go off of what's there, let me know if you have any questions on that.

Where are you getting stuck running in the dev container? You should be able to run python3 -m frigate in the terminal window.

I use this config for local dev:

cameras:
  back:
    ffmpeg:
      inputs:
        - path: /lab/frigate/airport.mp4
          input_args: -re -stream_loop -1 -fflags +genpts

@blakeblackshear Python isn't my primary programming language and I haven't developed any packages before, so was not familiar with the -m flag, I bet that will get me moving, thanks.

@blakeblackshear I got a No module named 'frigate.version' error, which looks like I can resolve using the Makefile. However, the dev. container does not have make in it, so I am going to have to do it outside the container. May be worth considering adding make to the container in the future.

[NickM-27]

@mathmaniac43 I believe you are supposed to make outside and then start the container. That's what I've always done

[blakeblackshear]

Building outside the container is listed in the docs here: https://docs.frigate.video/contributing#core

The command is now just make instead of make amd64_frigate. Feel free to fix that in the docs in this PR too.

@NickM-27 Makes sense, just fixed!

[NickM-27]

Looks good to me 👍
