[wpimath] PIDController field and method names for error and errorDerivative

[narmstro2020]

I replaced positionError with error and velocityError with errorDerivative across the fields and methods.

I also added a few items to the initSendable for tuning purposes.

Looks good, except the old PIDController error methods should be deprecated instead of immediately removed.

Will do. I need to finish up the C++ as well. I’ll challenge myself next time and do the C++ first.

Quick general question. Is a PR for RobotPy required only for commands or for every package. I have no problem making them. I just wanted to make sure not to break anything

RobotPy PRs are only needed for pure Python ports, like commands. The rest is autowrapped.

Robotpy is primarily done by wrapping C++. Only commands is done by writing pure Python, which is why there needs to be Python changes for changes in commands.
