message: Update README.md
  Bump three.js version requirement up to r111 - this is the first version
  that correctly supports morph targets with varying data sizes. Also
  remove the note about MESHOPT_ extensions since it's mostly unnecessary
  now - glTF-Validator is going to support KHR_quantized_geometry shortly.

  gltfpack can produce three types of output files:
  -- By default gltfpack outputs regular `.glb`/`.gltf` files that have been optimized for GPU consumption using various cache optimizers and quantization. These files can be loaded by standard GLTF loaders present in frameworks such as [three.js](https://threejs.org/) (r107+) and [Babylon.js](https://www.babylonjs.com/) (4.1+).
  -- When using `-c` option, gltfpack outputs compressed `.glb`/`.gltf` files that use meshoptimizer codecs to reduce the download size further. Loading these files requires extending GLTF loaders with custom decompression support; `demo/GLTFLoader.js` contains a custom version of three.js loader that can be used to load them.

  - When using `-cf` option, gltfpack outputs compressed files and an extra `.fallback.bin` file with uncompressed data. These files can be loaded by standard glTF loaders; loaders with decompression support don't need to load the fallback.
  -> Note: files produced by gltfpack use `MESHOPT_quantized_geometry` and `MESHOPT_compression` pseudo-extensions; both of these have *not* been standardized yet but eventually will be. glTF validator doesn't recognize these extensions and produces a large number of validation errors because of this.

  When using compressed files, `js/meshopt_decoder.js` needs to be loaded to provide the WebAssembly decoder module like this:
