radon: Use numpy.interp/scipy.interpolate.
...
Scipy supports all interpolation kinds (nearest, linear) we need, while
numpy supports only linear interpolation. The numpy interpolation is
substantially faster, so this is used even though it complicates the
code slightly.

iradon: Use util.pad for array padding.
...
This depends on util.pad accepting 0s in pad_width, which has a proposed
solution in gh-634.
