Add API method to deselect groups of points by track_id (passing a list maybe)?

[andyroo]

I'm not sure if this is the right way to do what I'm trying to do, but I've been trying to figure out a performant way to deselect points that are in different camera groups (see recent post and code) Everything I try takes minutes to deselect a few thousand points, and hours to select a few hundred thousand.

It's possible that I'm just "doing it wrong" but I tried all of my (not very much) skills and speeding things up and had no luck. Appreciate any help you can give.
