e172aa66f7 [wpimath] Java: add static instantiations of common rotations (#6563) 
C++ doesn't need this because it supports value types, which are much
cheaper to construct. constexpr is also available to make construction
zero-cost.

5359112b15 [wpimath] Deprecate RamseteController (#6494) 
LTVUnicycleController is a drop-in replacement with better tuning knobs.

The RamseteCommand examples were removed instead of retrofitted with
LTVUnicycleController because we're planning on removing the command
controller classes anyway, so it would be wasted effort. The
SimpleDifferentialDriveSimulation example shows direct
LTVUnicycleController usage.

5370f249a1 [build] Upgrade to wpiformat 2024.33 (#6449) 
This upgrades to clang-format and clang-tidy 18.1.1. This has the
constructor attribute formatting fix, so we can remove our
WPI_DEPRECATED macro.

a583ca01e1 [wpiutil] Change Struct to allow non-constexpr implementation (#5992) 
This required changing the constant values (e.g. kSize) into functions
(e.g. GetSize()).

Fixed implementations of ForEachNested to be inline (as these are actually
templates).

Also added a ntcore Struct test.

bb05e20247 [wpimath] Add protobuf/struct for trivial types (#5935) 
This implements de/serialization for the types that aren't templated (SwerveDriveKinematics) in C++ or where there is no trivial way to go round-trip (Splines) for the messages.

0ca1e9b5f9 [wpimath] Add basic wpiunits support (#5821) 
To reduce the need for users to manually perform unit conversions, this allows Measure objects from wpiunits to be passed into most places in wpimath that currently expect doubles in terms of SI units like meters.

For example, users would need to know that unit conversion is required - and what the correct units are. Using units would be more difficult to write code for than just hardcoding a value or using Units.inchesToMeters.

Now, using units has no more developer overhead than using raw numbers.

201a42a3cd [wpimath] Reorder TrapezoidProfile.calculate() arguments (#5874)

new for 2024.

0cf6e37dc1 [wpimath] Make LTV controller constructors use faster DARE solver (#5543) 
Made JNI modifications to expose the faster function, made the API use
the typesafe Matrix API, and synchronized the documentation with C++.

Sped up C++ LTV diff drive test from 20 ms to 15 ms.
Sped up C++ LTV unicycle test from 15 ms to 10 ms.

394cfeadbd [wpimath] Use SDA algorithm instead of SSCA for DARE solver (#5526) 
Both seem to work, but the SDA algorithm is specifically recommended for
solving DAREs as opposed to P-DAREs.

The QR decomposition was replaced with a partial pivoting LU
decomposition at the recommendation of section 2.4 of the paper.

More tests and a separate JNI function for each DARE solver variant were
added.
