Have a vector field visualization

[TheComputer314]

Is your feature request related to a problem? Please describe.
I am using the Pose2d arrow visualization for a vector field visualization (see attached) but when using that, the color/length of the arrow can't be changed to visualize magnitude, which makes it cluttered and hard to read. AdvantageScope also tends to get very laggy, since this method necessitates publishing hundreds or even thousands of Pose2ds in an array.

Describe the solution you'd like
A way to visualize a vector field in a way that is 1) more readable 2) more performant.

Describe alternatives you've considered
For my particular usecase, I could use the other visualization options that AScope has, but I would like the vector field visualization itself to have the magnitudes.

I originally had a wpimath PR that added a bound vector geometry type, but I closed that due to 1) the impl being kinda bad especially with naming 2) the use cases being too niche to be included in wpimath 3) it doesn't solve the performance issue of publishing a crap load of stuff to NT.

The problem is though that there's not really a good package/project to add a class for this use case. Adding it to wpimath was shot down for the above.
