description: 'layer resizable_stack for configurable component'
`resizable_stack` allows for variable size outputs on the generator. A conv stack is repeated until the output size is reached.
If you specify "segment_softmax" this repeats the pattern:
normalize(expects style vector named 'w')
activation(before last layer)
segment_softmax output_channels
* layer type. Defaults to "segment_softmax"
* segment_channels - The number of channels before segment_softmax. Defaults to 5
* max_channels - The most channels for any conv. Default 256
* style - the style vector to use. Default "w"
