@vsaw hope you review it and merge it to the new release if everything is ok,
thank you

@JooZef315 could you make a fork of it instead? I doubt it will be merged here

Sorry, I'm maintaining ODC and this Library as a hobby and got caught up in my day job. That being said I would like to merge this PR but don't have the time to fully review it therefore let me ask you a few questions and hopefully we can push through this way

1. is it backwards API compatible or does this require changes on ODC side to work
2. Could you check if your Code uses the ODC Code Style https://opendata.cam/docs/development/#code-style
3. Are there any Breaking changes in the libraries you updated as you skipped quite a few versions in your update

1- the breaking change now is that to use the tracker we have to make an instance of it first

import { Tracker } from 'node-moving-things-tracker';

const tracker = new Tracker();
tracker.updateTrackedItemsWithNewFrame(detectionScaledOfThisFrame, currentFrame);
const trackerDataForThisFrame = tracker.getJSONOfTrackedItems();

2- YES, it uses the ODC Code Style

I used the linter to check and it passes well.

3- No Breaking changes in the updated libraries

only uuid now has to imported as const { v4: uuidv4 } = require("uuid");

@JooZef315 Is there a way to keep it backwards compatible? E.g. by having a static default instance that will be used if people don't create separate instances?
