Update to TensorIO 0.6.x

• Small improvements and updates to our underlying machine learning interface
• Use the new .tiobundle extension for model folders instead of .tfbundle
• Add a "backend" field to the model object in model.json, set to "tflite" or "tensorflow". See model in our example app

Update to TensorIO 0.5.0

THIS IS AN API BREAKING CHANGE

More specifically, it is a dependency management breaking change. Podfiles must be updated to include the TFLight subspec. Change:

pod 'TensorIO'

To:

pod 'TensorIO'
pod 'TensorIO/TFLite'

And run pod update

Initial (updated) release

With support for image models and TFLite
