DepthwiseConv(size, in)
DepthwiseConv(size, in=>mul)
DepthwiseConv(size, in=>mul, relu)
Depthwise convolutional layer. `size` should be a tuple like `(2, 2)`.
`in` and `mul` specify the number of input channels and channel multiplier respectively.
In case the `mul` is not specified it is taken as 1.
Data should be stored in WHCN order. In other words, a 100×100 RGB image would
be a `100×100×3` array, and a batch of 50 would be a `100×100×3×50` array.
