[IKTweaks] Mistakes AprilTag Hip-locomotion Tracker for actual body tracker

[ronoverdrive]

AprilTag's Hip-locomotion driver provides a more natural Hip-based locomotion like the DecaMove-1 does, but with existing hip trackers (April Tag, Kinect, Vive Tracker, etc.). It does so by spawning a fake stationary tracker at the Play Space Origin at hip level with the serial number "Example_ControllerDevice" to provide locomotion direction. If you calibrate close to the PSO it will mistake the fake tracker for your hip tracker. As of right now the only fix I've seen is to move to the far end of your play space and recalibrate to get IKTweaks to ignore the fake tracker.

Ex from my log showing it attaching to the fake tracker. [23:09:06.212] [IKTweaks] Found tracker with serial Example_ControllerDevice for point Hip

Two possible fixes might be to either add a blacklist option for Example_ControllerDevice or if possible get the tracker definitions direct from SteamVR to learn what tracker is defined to what body part and ignore the rest. The later would probably be the more ideal solution if possible.
