0ef8a4e1df [wpimath] Support formatting more Eigen types (#4391) 
Added an Eigen::SparseMatrix formatter.

Also modified the Eigen::Matrix formatter to support Eigen::MatrixXd.
Eigen::MatrixXd sets both dimension template arguments to -1, so they
can't be used for iteration. rows() and cols() are now used instead.

rows() and cols() are constexpr for statically sized matrices, so
there's no performance loss there.

ac9be78e27 Use stricter C++ type conversions (#4357) 
Now, implicit narrowing conversions are only used with wpi::Now(). This
also fixes clang-tidy warnings about C-style casts. For example:
```
== clang-tidy /__w/allwpilib/allwpilib/wpilibNewCommands/src/main/native/include/frc2/command/SwerveControllerCommand.inc ==
/__w/allwpilib/allwpilib/wpilibNewCommands/src/main/native/include/frc2/command/SwerveControllerCommand.inc:95:18: warning: C-style casts are discouraged; use static_cast/const_cast/reinterpret_cast [google-readability-casting]
  auto curTime = units::second_t(m_timer.Get());
                 ^
```
In that case at least, the cast was removed entirely since Get() already
returns a units::second_t.

151dabb2af [wpiutil] Upgrade to fmt 9.0.0 (#4337) 
fmt removed fmt::make_args_checked since it's no longer needed for
constexpr format string checks.

fmt deprecated implicit conversions from enums to integers in format
arguments, so I added explicit static casts.

dc6f641fd2 [wpimath] PIDController: Reset position and velocity error when reset() is called. (#4064) 
In addition to m_prevError and m_totalError, m_positionError and
m_velocityError need to be reset to 0 when reset() is called.
Otherwise, the next time calculate() is called, the old values will be
used as the previous error, but this is inaccurate since the caller
wanted to reset the state of the PID controller.

system model.
