+The PhotonPoseEstimator has a constructor that takes an `AprilTagFieldLayout` (see above), `PoseStrategy`, `PhotonCamera`, and `Transform3d`. `PoseStrategy` has nine possible values:
 
 - MULTI_TAG_PNP_ON_COPROCESSOR
     - Calculates a new robot position estimate by combining all visible tag corners. Recommended for all teams as it will be the most accurate.

 ### `setLastPose(Pose3d lastPose)`
 
 Update the stored last pose. Useful for setting the initial estimate when using the CLOSEST_TO_LAST_POSE strategy.
