v2.1.0 - Add eyelook data

This release adds the eye rotation information that the Quest pro captures. This is a drop in replacement for v2.0.0 which requires no additional setup ingame. This also incorporates Geenz's jaw fixes,

Known issue: The eye look up/down/left/right blend shapes don't work. This is most likely due to the combined eye data not being set up properly. This is a small enough issue that I've decided to push this completed release first.
