> Add a new 2D depthwise convolution layer

> Key: SYSTEMML-1674

> Project: SystemML
> Issue Type: Sub-task

>
> A depthwise convolution (1) applies a different set of M filters to each
> input channel separately, thus expanding each input channel to M output
> channels, and (2) concatenates the results into a single volume with C*M
> output channels. This is in contrast to a regular 2D convolution, in which
> all of the filters would be applied to all of the input channels at once.
