- Remove duplicate motor port (2) from C++ SwerveBot/SwerveDrivePoseEstimator
Java has the correct motor ports.
- Fix duplicate port allocation in C++ RomiReference by correcting if/else check
Java logic was already correct, and confirms this change.
A lot of these are breaking changes. frc::Timer was replaced with the
contents of frc2::Timer. The others were in-place argument changes or
removing deprecated non-unit overloads.
Also deprecate SpeedController in favor of motorcontrol.MotorController and
SpeedControllerGroup in favor of motorcontrol.MotorControllerGroup.
The MotorController interface is derived from the SpeedController interface
so that code such as SpeedController x = new VictorSP(1) continues to
compile (just with a warning).
SpeedControllerGroup and MotorControllerGroup are independent classes;
both implement the MotorController interface.
Flip the TeleopArcadeDrive axis directions so that positive
values for x-axis speed result in the Romi driving forward (in the
direction of the Raspberry Pi USB ports).
