Alpha Release #6.0.7

"Region of Interest" (ROI) optimization is now enabled by default

• NOTE: If you already ran the alpha 6.0.6 build then you'll need to manually set "disable_roi" to false in your TrackerManagerConfig.json file since the old default has already been saved out.

Fixes for ROI

• Checking against the wrong flag to see if the previous frames projection was valid
• Don't modify trackerPoseEstimateRef.bCurrentlyTracking until after call to tracker->computeProjectionForController
• Fixed projection area calculation to use pixels instead of normalized screen coords for ellipse
• Made min ROI size 32 pixels instead of 10
• Added "min_valid_projection_area" config value to tracker manager config
  • contours smaller than this size (pixels^2) are rejected if an ROI region smaller than the screen is used

Assorted Crash/Assert Fixes

• Fixed uninitialized trackingColorType in compute tracker poses tool
• Fixed divide by zero issue with cv:moments in tracker code
• Fixing slightly un-normalized quaternions in LightBar optical orientation quaternions

Assorted Fixes for DS4 support (in progress)

• Enable LightBar tracking in orientation test for DualShock4
  • Optical weight calculation in OrientationFilterComplementaryOpticalARG was completely broken
  • Yaw blending doesn't seem to be working correctly in OrientationFilterComplementaryOpticalARG,, reverted to pure quaternion blending for the moment
