Demo is broken

[Nexuist]

Hi, just wanted to let you know the demo linked in the README is broken due to a CORS error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://s3.amazonaws.com/neocortex-js/examples-data/mnist_mlp_sample_data.json.gz. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 404.
