Improve interoperability with scipy

[haesleinhuepf]

This is for @tlambert03 @jni ;-)

I extended the API to be compatible to both worlds (clij and scipy). I added parameters such as axes and angle to rotate and matrix to affine_transform. Furthermore, I added the aliases zoom forwarding to scale and shift forwarding to translate. Also those two have the right parameters to be compatible to scipy (to some degree). I'm considering to make them independent functions, and no aliases, that would mean doubled functionality, but it might be easier to maintain. What do you think?

More sophisticated parameters such as mode{‘reflect’, ‘constant’, ‘nearest’, ‘mirror’, ‘wrap’}, optional in zoom and order in affine_transform are a bit above my abilities. PRs welcome ;-)

Check out the notebook for details (edit: link fixed)

Put this in "Draft" state again, because I'd like to change the API as discussed in #49 (comment)
