e767605e94 [wpimath] Add typedefs for common types
This makes complex code significantly easier to read.

frc::Vectord<Size> = Eigen::Vector<double, Size>
frc::Matrixd<Rows, Cols> = Eigen::Matrix<double, Rows, Cols>

181723e573 Replace .to<double>() and .template to<double>() with .value() (#3667)
It's a less verbose way to do the same thing.

9359431bad [wpimath] Clean up Eigen usage
* 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()

f9c3d54bd1 [wpimath] Reset error covariance in pose estimator ResetPosition() (#3418)
This also fixes a member function name inconsistency between languages
and adds missing documentation to C++'s KalmanFilterLatencyCompensator.

Fixes #3229.

d1c7032dec [wpimath] Fix order of setting gyro offset in pose estimators (#3176)
The gyro offset should be determined from the desired initial pose, not the current pose. This fix reflects the behavior of the odometry classes and the C++ holonomic pose estimators.

f393989a5b [wpimath, wpiutil] Add wpi::array for compile time size checking (#3087)
The wpimath APIs use std::array, which doesn't do size checking. Passing
an array with the wrong size can result in uninitialized elements
instead of a compilation error.

This is a breaking change but is worthwhile to avoid hard-to-debug errors.

8f1f64ffb6 Remove year from file copyright message (NFC) (#2972)
Also update copyright to include "and other WPILib contributors" and clarify
license referral language to not be restricted to FIRST teams.

bc8f338771 [wpilib] Add pose estimators (#2867)
Pose and state estimators can filter latency-compensated global measurements and fuse them with state-space drivetrain model information to estimate robot position. They are drop-in replacements for the existing odometry classes.
