0.2.0

• replace WASD+mouse navigation with OrbitControls based on three.js:
  • rotate: left click + drag
  • pan: right click + drag (still a bit buggy after rotation/zoom)
  • zoom: mouse wheel
• add --count parameter (short -c) to generate multiple screenshots, rotating evenly spaced around the object (#10)
• add --headless parameter for real headless screenshot generation. Unfortunately it only works on macOS. For a workaround using xvfb/Docker see here.
  • Docker images are automatically built for each branch & tag: https://hub.docker.com/r/bwasty/gltf-viewer/
• change background for screenshots to be transparent
