Removed PIDTargetY.

The lifter will no longer use a PIDController to target on the Y axis.
Added Lifter targeting system to VisionTrackingCommand.

The VisionTrackingCommand will now use a Relay instead of a PID controlled
motor controller. LifterTargetY.java will compute and output the targeting
data.
