fix:: replace scipy.misc with imageio and skimage

[brendalf]

As stated by @ML-Chen in #2, scipy.misc.imread and scipy.misc.imresize has been deprecated and is no longer available with recent versions of scipy.

Instead, we can replace it with from PIL import Image.

Solves #2.

If I may suggest, I would rather directly replace it with Pillow i.e.

from PIL import Image

img = Image.open(file)
img = np.array(img.resize((299, 299), resample=Image.BILINEAR))

Done. Thank you, @ludgerpaehler
