Redundant OpenVINO dependency

[mgagvani]

The road-segmentation-adas-0001 model in models/ is used to segment out extraneous background when training on a racing game such as Forza Horizon. Currently, it runs through Intel OpenVINO toolkit. There is a large problem with this approach, however: it won't work on systems with ARM/AMD CPUs.

In order to make the approach of segmentation more viable, the OpenVINO IR (Intermediate Representation) model should be converted to a TensorFlow model for GPU acceleration. https://github.com/PINTO0309/openvino2tensorflow looks like a good resource.
