v1.8.0

- Added Brazilian Portuguese lip-sync language module (contributed by @boemekeld ) 🎉
- Bumped three.js version from r180 to r186
- Added Meshopt compression support. See README, Appendix A.
- Added support for skeleton adjustment (retargeter.mjs). The basic idea here is that some minor rig adjustments can be done automatically when loading the avatar instead of needing to fix each 3D character in Blender separately. See example configs tailored for different avatar creators in README, Appendix A.
- Minor fixes and improvements

PS. Also check out the latest release of the [MotionEngine](https://github.com/lhupyn/motion-engine) plugin by @lhupyn that can now use a decision model to choose appropriate expressions and gestures for the TalkingHead avatar in real-time.
