Simplify local build on MacOS

[JCGoran]

pip install . should just work now, provided the user follows the README exactly.
Also updated instructions for specifying wheel version of COFFE when using cibuildwheel.

I still get error:

Should be fixed now (see new instructions), git's default of not cloning submodules was the issue.

Better, bur there is another error:

For contest, I reinstalled and gitcloned everything again but I got this

2 options to resolve this:

1. Use sudo in front of whatever command you are running
2. set the environmental variable CLASS_INSTALL_DIR and CUBA_INSTALL_DIR to some dirs that don't require elevated permissions via export CLASS_INSTALL_DIR=/some/other/dir

[fsorrenti]

sudo works, but we have problem related to class installation 'stdio.h file missing'

fatal error: 'stdio.h' file not found

Since that's a system header, I suspect your compiler config is probably broken, so maybe this could help? In which case the answer could be running:

export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)

Afraid I cannot be of more help since everything works on my machine.
