Radon transform: Include boundary in reconstruction circle.
...
A test criterion needed to be relaxed slightly to have tests still
passing. This is ok, as the reconstruction circle is now larger, meaning
larger errors should be expected. Moreover, the test in question uses
random data, and changing the seed causes greater changes in accuracy
than the amount the test criterion was relaxed by.

Radon transform: Redefine projection center for sinograms.
...
This definition is chosen because it is simple to express in the
documentation. No changes in accuracy are to be expected, but comparing
sinograms and reconstructions before and after this commit will give
different results in the cases where ``circle=False`` for ``radon`` or
``iradon``.

iradon: Only allow interpolation methods working well.
...
Of the interpolation methods provided by scipy.interpolate.interp1d,
only cubic has been found to work well with the tests in skimage (other
methods are either identical to linear or nearest, or they produce bad
reconstructions).

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.
