Major Changes

Linked waypoints at the start/end of paths will now link the start/end rotations. For instance, changing the end rotation of path A will update the start rotation of path B if the end waypoint of path B and the start waypoint of path A are linked
Added support for passing in arbitrary PathConstraints to SwerveSetpointGenerator. This allows limiting the max velocity/acceleration of the robot below its maximum capabilities, such as limiting max acceleration based on the height of an elevator.
Added the ability to mirror paths and autos from the left side of the field to the right and vise versa. path.mirrorPath() and new PathPlannerAuto("Auto Name", true)
Fixed incorrect trajectory flipping
Added an annotated version of the 2025 field image, which labels each reef pole
Various bug fixes
