API: expose `axis` keyword in pandas.core.algorithms.take
I haven't quite replaced cyberpandas' take with pandas' yet. I think one reason is that I need to be able to pass axis through to `pandas.core.algorithms.take`

We'll have to be careful. The default for `take_nd` is 0, while for `ndarray.take` it's None. I think we want the default to be 0.

I still have to figure out one other thing, but then hopefully things will work.
