Improves accuracy

* by implementing the stacked hourglass backbone

* by increasing the number of 3D convolutional layers for cost aggregation

(+) The large memory and computation cost incurred by using 3D convolutions is reduced

(-) frequent down-sampling and up-sampling loss of precision in the disparity map
