Version 1.4.0 release

• WASM and JavaScript decoders are hosted from a static URL.
  • It is recommended to always pull your Draco WASM and JavaScript decoders from this URL:
  • https://www.gstatic.com/draco/v1/decoders/*
    • Replace * with the files to load. E.g.
    • https://www.gstatic.com/draco/v1/decoders/draco_decoder_gltf.wasm
  • Users will benefit from having the Draco decoder in cache as more sites start using the static URL
• Changed npm modules to use WASM, which increased performance by ~200%.
• Updated Emscripten to 2.0.
