Drop 2to3

python2 is dead, and python3.11 dropped support for 2to3, so its use in setup.py creates problems during installation. Let's just rewrite the code (using 2to3) to python3.

 ## Requirements
 The most basic features of DEAP requires Python2.6. In order to combine the toolbox and the multiprocessing module Python2.7 is needed for its support to pickle partial functions. CMA-ES requires Numpy, and we recommend matplotlib for visualization of results as it is fully compatible with DEAP's API.
 
-Since version 0.8, DEAP is compatible out of the box with Python 3. The installation procedure automatically translates the source to Python 3 with 2to3.
