Quick user-specific calibration

[lassoan]

Calibration tool in settings optimizes display for a specific user. Internally, it computes the interpupillary distance (IPD). If it is not set correctly, then the hologram appears to be shifting when the user translates his head left-right.

There does not seem to be UWP or Unity API to set IPD, but a side-loaded application can set it by connecting to the device portal - see https://github.com/jbienzms/HoloTools/tree/master/FitBoxIPD.

If we find that correct IPD is essential then maybe we can implement a quick IPD switching feature (we would store each user's IPD and set the correct one when the headset is passed on to another person).
