Hotfix Blinking with Openness

This is a Hotfix release for the new Openness Float, or rather a refactoring job that accompanied the release.
Turns out the Tracking status turns "Invalid" when the user blinks, preventing the eyelids from ever closing fully facepalm
This Hotfix patches that.

Update: Also added a version compiled with the Pupil Diameter param support (for those who already use a version of VRCFT with support for that)
