                 Summary: Allow functions in ImageArithmetic => Function for
operations on specific pixels in an image

Eversince commit 249a0e056
<http://git.savannah.gnu.org/cgit/gnuastro.git/commit/?id=249a0e056d0cafa6da97c065aab702dcf9bfa9d4>
functions have been defined in Arithmetic. But it seems I had forgot to tag
this task as closed.

But besides pure functions that operate on all pixels, the last example in the
comments of task #13574, had a unique function called `where' (taken from
Numpy's `numpy.where' function). This unique function will allow setting
values for special pixels in the image, not all pixels.

I am now busy implementing this feature, it requires the definition of
conditionals which have mostly been done, so I don't expect it to take too
long.
