This is a cleanup of the FlywheelSim class with a few added features.
- One FlywheelSim constructor that takes a plant, DCMotor, and a optional number of measurementStdDevs. The documentation now states how to construct the plant either through LinearSystemId.createFlywheelSystem or identifyVelocitySystem.
- The gearbox, gearing and moment of Inertia (J) are now private final fields. The gearing is determined from the plant in the constructor as well as the moment of inertia. There are getter methods that allow the flywheelSim to return the gearbox, gearing, and moment of inertia.
- The getCurrentDrawAmps function now uses m_x instead of getAngularVelocityRadPerSec in accordance with more accuracy and matches the patter in other sims.
- Added getter methods for the InputVoltage, angularAcceleration and torque
- (Java only) A third getter method for returning the AngularVelocity of the flywheel using a MutableMeasure as a backing field that is set when getAngularVelocity is called. This summarily returns the angularVelocity as just a Measure object. This allows the user of this class to handle unit conversions with less numerical manipulation. Alterations in C++ for this feature were not needed.
Modified Java constructors to take a variable number of measurement std devs argument with checks in place to make sure the right amount (or none) are passed into the constructor. All changes passed down to classes utilizing LinearSystemSim.
Removed excess constructors
Removed Java and C++ CurrentDrawAmps method as it doesn't belong in a generic (non electrical) linear system. Kept a non override version in all derived electrical classes.
Also LinearSystemSim has now been made agnostic to electrical systems. Inputs don't have to be voltage. BatteryVoltage clamp function has been pushed down to electrical subclasses.

* Replace Matrix<> with Vector<> where vectors are explicitly intended.
I found these via `rg "Eigen::Matrix<double, \w+, 1>"`.
* Pass all Eigen matrices by const reference. I found these via `rg
"\(Eigen"` on main (the initializer list constructors make more false
positives).
* Replace MakeMatrix() and operator<< usage with initializer list
constructors. I found these via `rg MakeMatrix` and `rg "<<"`
respectively.
* Deprecate MakeMatrix()
This includes physics simulation support for arms/elevator models, as well as differential drivetrains.
Swerve might be added at a later date.
