Now that so many trackers are supported, and all combinations are supported as well, SteamVR tracker roles should be respected when they're set. This would apply on top of the calibration range and help avoid issues like an elbow tracker mapping to the chest.

As well, the Disabled role should apply, so a tracker could still be within the calibration range but unused by VRChat. I can't think of a use right now, but Im sure there's some.
