Conv2d image shapes

Created by: benjaminkreis

I don't fully understand the problem yet, but we have a bug in defining the image shapes of Conv2ds.

I have a model where the height and width of a second Conv2d is being assigned the height and width of the first Conv2d.

Relevant code: https://github.com/hls-fpga-machine-learning/hls4ml/blob/master/keras-to-hls/keras-to-hls.py#L234-L235 https://github.com/hls-fpga-machine-learning/hls4ml/blob/master/keras-to-hls/keras-to-hls.py#L280

I'm investigating
