Coordinate systems

There are three coordinate systems in use in the codebase. The WPILib coordinate system (CoordinateSystem::WPILIB) is used when reading from WPILib-provided config files and in communication with the roboRIO (WIP). The THREE.js coordinate system (CoordinateSystem::THREEJS) is used throughout most of the codebase and when communicating with Titan-Dashboard. The OpenCV coordinate system (CoordinateSystem::OPENCV) is used for the results of certain OpenCV functions, such as cv::solvePnP.
