Cloud GPU / TPU TFJS Challenge.

Train and Save this Tensorflowjs Model on your Cloud service and tweet to @rocksetta the lowest training time (in seconds) and the lowest cost (in pennies)

When you are done, tweet something like:
Hey @rocksetta here is my #cloudTfjsChallenge results: Cloud service website (as a URL), train time (in seconds), cost (in pennies), Optional: saved model (as a URL)

Note: I have made this model a fair bit bigger than needed to drag out the training session.
