High-level additions

  • Kernel modularization has begun! This will not affect any code today but in
    the future we'll add support for dropping code for kernels not used for your
    model.
  • The WebAssembly backend is now on NPM in alpha. You can check out details in the
    README (here)[https://github.com/tensorflow/tfjs/tree/master/tfjs-backend-wasm].
    We're not listing all the WASM PRs here yet, this will happen with the first non-alpha
    release.
