Wrap Maxima's residue calculation

[kcrisman]

I can't believe we haven't done this before, nor that someone hasn't requested it. See this ask.sagemath post.

sage: f(x)=1/x
sage: f.maxima_methods().residue(x,0)
1
f(x)=1/(x^2+1)
f.maxima_methods().residue(x,i)
-1/2*I

This should be a little easier to do than that.

Apparently Sympy also has this. See for example this answer to an ask.sagemath.org question by achrzesz.

Also, when we do this, we should probably point out the bug that apparently is in Maxima there. I don't see a point in making a ticket for that until we actually wrap it, though.
