Add fast wavenet generation.

See original GitHub issue

@ibab I noticed you saw the efficient wavenet generation implementation I wrote with my friends:

https://github.com/tomlepaine/fast-wavenet

Can we help you add it to tensorflow-wavenet?

Update: Just about finished with the port. Will clean up the code and run some speed tests tonight, then make a pull request.

Sorry for the delay!

It seems like the way we implemented our queue had a bug that made the states we pop incorrect a small percent of the time. We aren’t sure of the exactly cause, but we think it is related to tf.scatter_update. We switched from our queue to tf.FIFOQueue and it seemed to fix the bug (and slightly improved our speed 🎉). Now (based on our tests) the fast generation exactly reproduces outputs and states of the slow generation.

We will make a pull request after lunch.
