Move ndarray library to its own repository

[karllessard]

The Java NdArray library now have its own repository, to emphasis its independence from TensorFlow itself and allow it to have its own development/release cycle.

As part of the review of this PR, please take also a look at the new repository : https://github.com/tensorflow/java-ndarray and let me know if you see anything that should be changed there as well.

A note on this, I've moved the library as a sub-module since we might end up having other modules there as well, e.g. ndarray-kotlin. Also, I've picked tensorflow-java-ndarray as the name of the parent module so it matches the name of the repo (like tensorflow-java matches this one) but I guess this is also debatable.

Sounds alright and looks fine, but did you want me to look at something in particular?

Just one thing, we probably want to set the version to 0.4.0-SNAPSHOT instead of 0.3.1.

Nothing in particular, was just seeking for a general feedback like this one, thanks. The version is 0.4.0-SNAPSHOT btw, it’s just the example in the README that shows the usage of the last released version.

Since we're probably going to end up with more modules, maybe we could rename the "ndarray" one to "ndarray-core" or something?

I think I still prefer the simplicity of org.tensorflow:ndarray for importing the main artifact of that library, then append a -something to any of its upcoming extensions.

Ideally we would have done the same with tensorflow but org.tensorflow:tensorflow was already being used by TF 1.x

Ok I’ll take this as a go, thanks!
