This adds the ability to select multiple bounding boxes at once. This allows
managing labels for many boxes at one time.

I'm posting this now just so that people can look at this. This code is very
and have evolved in private but I'd like to see it in CVAT proper eventually.

Related: #5473

Motivation and context

We work with images that are over 1GiB and that have 100s of bounding boxes.

How has this been tested?

In (our) production.

@nmanovic Here is our code. It's not pretty, and I don't know enough about CVAT to offer pre-emptive help. Feel free to ask questions, though. I'll see if I can get you answers.

@docwhat , thank you for the contribution. It looks like current patch has a lot of merge conflicts. It will require significant efforts from our team to adapt these changes and cover them by tests. As discussed in the meeting, we are ready to take the task and probably others if you need that. Happy to help our customers.

Would love this feature (click and drag to multi-select boxes and delete or relabel)

[bsekachev]

I will close the PR for now. If you are ready to carry on you work, you are always welcome

[docwhat]

Alas; the company I was doing this work for is gone. Sorry. Maybe someone else will be interested in pulling apart the patch.

This would be great. :)
