Can't Install on Mac OSX 11.x (Big Sur)

[bxg682]

Assuming I understand the below error correctly, could you please add support for installation on Mac OSX 11 (Big Sur)? Thanks for all you do!

@bxg682 This is probably more of a Big Sur & Python 2.7 issue than it is a py-earth issue. Try installing on Python 3 instead.

fyi, i was able to install and run py-earth on macos 12.6.1 (monterey) that had python 3.10.8 using a slightly different build sequence than noted in the readme:

git clone https://github.com/scikit-learn-contrib/py-earth.git
cd py-earth
sudo python setup.py install --cythonize

then when you try to run the example script noted in the readme, dont try to run it from the py-earth folder, put that script in another folder and run it from there (or else an error will occur due to it trying to load modules from the py-earth folder you just built from, which causes runtime errors)

found this out by combining some info from various stack overflow posts and other posts in this repo

git clone https://github.com/scikit-learn-contrib/py-earth.git
cd py-earth
sudo python setup.py install --cythonize

Thank you! I am able to install pyearth this way on Ubuntu 20.04 and Python 3.10.
