Allow for the more current TensorFlow models

[oblitzitate]

Use case

Apparently the SVM models are outdated by now. And that the current TensorFlow models have significantly better performance in terms of accuracy and generalization.

I haven't actually tested it myself, but I figured I'd let you know.

Solution

Allow to use the more current TensorFlow models instead.

@oblitzitate - I am sure you are right.
I will put this on the list when preparing a new release. Thanks.
