Removing readline as a dependency on unix to avoid implicating GPL3 licenses

While auditing our python distribution, we discovered that the python version built by conda-forge could be required to be distributed under a GPL3 license, which is not viable for commercial purposes.
This arises from the fact that the python library is built with readline, which is GPL3.

Given that this could create some issues for commercial distribution of conda-forge/python, what are your thoughts on removing it? A possible replacement is libedit

(I know this is easy to do, and I'm trying it out, but for some reason I'm not able to run docker image to build locally. So in the mean time, I thought I would ask the community while I try to debug my situation and test this change)
