Keras: [Feature Request] Lattice layers

[zachmayer]

I'm not sure how to make a feature request, but lattices in tensorflow look really cool, and I'd love to see lattice layers in keras.

• [x] Check that you are up-to-date with the master branch of Keras. You can update with:
  pip install git+git://github.com/keras-team/keras.git --upgrade --no-deps

• [x] If running on TensorFlow, check that you are up-to-date with the latest version. The installation instructions can be found here.

• [x] If running on Theano, check that you are up-to-date with the master branch of Theano. You can update with:
  pip install git+git://github.com/Theano/Theano.git --upgrade --no-deps

• [x] Provide a link to a GitHub Gist of a Python script that can reproduce your issue (or just copy the script here if it is short).

Hey Zach. We are working on a Keras layer implementation of the TF Lattice library. It will have TF backend with both TF 2.x eager support and TF 1.x legacy support.

That is awesome! Thank you!
