5b73c17f25 Remove encoder velocities methods in DifferentialDriveOdometry (#2147) 
It doesn't make sense to continue to provide a less accurate method of performing odometry
when a more accurate method using distances exists.

This also removes the need to pass DifferentialDriveKinematics to the constructor.

2622c6c291 Add default values for b and zeta in RamseteController (#2145) 
Values b=2.0 and zeta=0.7 have been well-tested to produce desirable results.

f66ae59992 Add HSV helpers to AddressableLED (#2135) 
Also change the setLED() method to setRGB() for consistency and clarity.

Add rainbow example to demonstrate HSV usage.

5e97c81d80 Add MedianFilter class for moving-window median (#2136) 
This kind of filter is extremely useful for signals that are susceptible to sudden
outliers - ultrasonics, 1-D LIDAR, and results from vision processing are all
good use-cases.

This also modifies the existing ultrasonic examples accordingly.

f79b7a058a Remove unnecessary constructor arg for LinearFilter's circular buffers (#2140) 
They are initialized in LinearFilter's constructor, so the default is
never used.

ffa4b907c0 Fix C++ floating point literal formatting (#2114) 
Found formatting errors with this regex
"([^a-z0-9\.]\.[0-9]|[^a-z0-9\.][0-9]\.[^a-z0-9\.])" and ignored false
positives.

Fixes #2112.

845aba33fe Make feedforward classes constexpr (#2103) 
ArmFeedforward::Calculate() can't be made constexpr because std::cos()
and thus units::math::cos() is not constexpr.

Fixes #2101.

841ef91c0f Use gyro angle instead of robot angle for odometry (#2081) 
The odometry classes previously took in the robot angle as an argument, meaning that users had to take care of offsetting the gyro themselves to accurately report the robot angle. This change will make it so that users will not have to worry about resetting gyros and adding offsets themselves, as this will be handled by the odometry classes.
