Test the CNN implementation for robustness to hyperparameter changes

[charlesfrye]

in particular, how much can i change the sizes of the convs before the adaptive pooling layer complains? how much can i change the target size of the adaptive pooling layer? how deep can i go before MNIST images are too small?

looks like the adaptive pooling is hella robust, so we don't need to worry too much.

i have also chosen solid starting HPs to encourage high performance + over-fitting at the start.
