ad18fa62ee [wpilib] Add LED pattern API for easily animating addressable LEDs (#6344)
Add LEDReader and LEDWriter helper interfaces to facilitate composing simple patterns into more complex ones, e.g. LEDPattern.solid(Color.kBlue).breathe(Seconds.of(0.75)). Pattern composition relies on changing out the write behavior; for example, offsetBy increments the indexes to write to; while blink will switch between playing a base pattern and turning off all the LEDs.

Add a view class for splitting a single large buffer into smaller distinct sections, which is useful for dealing with long chained LED strips mounted on different parts of a robot. Views cannot be written directly to an LED strip (in fact, trying to do so won't even compile).

Adds some utility methods to the Color class for interpolating between two colors, and support color representations with 32-bit integers to avoid object allocations.

ab315e24c8 [wpimath] LinearSystemSim Constructor and method cleanup (#6502)
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.

fc56f8049a [wpilib] DriverStation: Change alliance station to use optional (#5229)
Many teams have issues trying to read the DS too early. By switching to an optional, we cause teams to check 2 things. Either 1) they explicitly check, and their code is correct, or 2) they just read .value() and their code reboots in a loop. However, because the DS will eventually connect, this 2nd case is ok, and should theoretically be undetectable on the field.
