Add TuneG, TuneS, and TuneV to wpi_interface.feedforward_tuning

[aidnem]

Adds the following classes for feedforward tuning under wpi_interface.feedforward_tuning:

• TuneG
• TuneS
• TuneV

Also add coppercore.controls as a dependency of wpi_interface. UNTESTED - This code needs to be built and tested before it is used, as it wouldn't build properly in GitHub codespaces.

I'm getting the following error and can't really figure out how to fix it:

/__w/coppercore/coppercore/wpi_interface/src/main/java/feedforward_tuning/TuneS.java:9: error: cannot access Sendable

I'll work on it some more when I get home to try and fix it but if anybody knows what's wrong please tell me :)

Note to self for later: Apparently I need to update WPILib or something?.
@jkleiber if you believe this falls under your domain of devOps issues, I would gladly accept some assistance about why none of my imports are working. If you have more important things to do, no worries, I'll probably figure it out.
