Add keras model module to VGGish project

[rola93]

This repo is amazing, I mean, VGG-ish is a powerfull model, but tensorflow is a little bit complicated. However, Keras is far more easier to learn. Now a days keras is part of tensorflow itself, so here goes my question/suggestion:

have you considered adding this particular module to the original VGGish project?

For me, it looks like a great idea to keep it all together, I'd definitely do it, but perhaps you already tried it

Thanks
