Grouped Convolution Block

[carlosrivera22]

I'm not sure about the implementation of the grouped convolution block. The attached image shows a different approach if I'm not mistaken. The repository has only one convolution per tower while the image shown has 3 convolutions followed by BatchNormalization and Relu, except for the last one which is only followed by BatchNormalization.
