Show Vive Tracker ID / StreamVR role in 3D space

[chrisnovello]

Would be awesome to have small (maybe optional) text labels attached to each tracker with metadata like ID and Role it has in Steam VR settings.

SteamVR currently makes it very confusing to work with multiple trackers, this software is a life saver on many levels. Having that info visible could prove quite useful for many people (even just 3 tracker IK rigs, it can be easy to accidentally use the wrong tracker for calibration). Could be a toggle to keep overlay clean for those that dont want the text info, and maybe not as necessary with controllers where handedness is more evident?

Love this software, very grateful, incredibly useful, thank you so much for your work !!
