0d30108dcb [wpiutil] Endian.h: minor cleanup and improvements (#2454) 
- Make use of if constexpr when possible for byte_swap
- Remove unnecessary make_unsigned_t alias (added to STL in C++14)

35eb90c135 Fix "'dimensionless' ambiguous symbol" error (#2382) 
A typedef for units::dimensionless::dimensionless is defined, which
conflicted with the namespace when we added "using namespace
dimensionless". This patch reverts the "using namespace" directive.
"using" directives were added to pull three of the four relevant
typedefs but avoid the "dimensionless" type conflict.

This issue was first introduced in #2301.

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.

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.

971303da8c Add PortForwarder class (#1890) 
This class provides an easy way to forward local ports to another host/port.
This is primarily useful to provide a way to access Ethernet-connected devices
from a computer tethered to the RoboRIO USB port.

The most natural spot to put the shared implementation of this class was into
wpiutil, so a wpiutilJNI library has been added.

7e95010a29 Add compile-time EJML matrix wrapper to wpiutil (#1804) 
This adds a wrapper over EJML's SimpleMatrix that uses generated classes representing numbers to encode the dimensions of each matrix at compile time, and to check operations between matrices for validity at compile time, rather than failing with an exception at runtime. This is required for the Java implementation of state-space control.

Additions to the wpiutil gradle script, and a python script at the wpiutil root are used to generate numeric types from a template at build time for both gradle and cmake. Users will be able to access types through functions on the Nat class.

c98ca7310f Add EJML dependency to wpiutil (#1769) 
Add EJML as the Java library for linear algebra for use in wpilib. This is equivalent to Eigen for C++.

The EJML dependency is downloaded in cmake and pulled in via maven in the gradle build.

04c9b000ff Revert "Fix build of Eigen 3.3.7 with GCC 9" 
-Wextra adds -Wdeprecated-copy, which Eigen emits. We're going to
squelch the warning instead to minimize changes to Eigen's upstream
sources.

2f680ba990 Add Eigen linear algebra library 
This imports Eigen 3.3.7, which will be used by the wpilibc implementation of
state-space control and mecanum/swerve forward kinematics (the forward
kinematics requires least-squares solutions via a matrix pseudoinverse).

While Eigen has parts licensed under BSD, MINPACK, and MPL2, the files we need
are only MPL2.
