math.ceil where it should be math.floor

[koltenpearson]

in dump_filters.py, in the make_padding function

def make_padding(padding_name, conv_shape):
  if padding_name == "VALID":
    return [0, 0]
  elif padding_name == "SAME":
    return [int(math.ceil(conv_shape[0]/2)), int(math.ceil(conv_shape[1]/2))]
  else:
    sys.exit('Invalid padding name '+padding_name)

math.ceil should be replaced with math.floor in the "SAME" branch. Not doing so results in errors about the size of the padding vs the kernel size of SpatitalAveragePooling when attempting to run the model.
