Use CMake and cibuildwheel, take 2

[JCGoran]

After some trial and error, I think I managed to get COFFE to work seamlessly on both Linux and MacOS (both arm64 and x86_64) using CMake as the build system.
Refer to the README to see how it works, but the short version for how to build COFFE (the Python version at least) on MacOS is:

• make a Python venv and activate it
• then either (the two approaches can be mixed and matched, but I don't recommend it):
  • install Conan via pip install conan and install the third-party dependencies conan profile detect --force && conan install . --output-folder=_build --build=missing
  • install the third-part dependencies via Homebrew brew install fftw gsl libconfig
• finally, install the "other" dependencies with bash scripts/install_other.sh cuba class (sudo may be needed since it's writing to /opt)
• install COFFE with pip install .. Optional dependencies (for testing, docs, etc.) can be installed with pip install '.[all]' (note the quotes around, you need them)

For testing, you can do python -m pytest -vvv tests/ (note that this may take some time to run).

To make a Python version of COFFE you can send to others, you can do:

• make a Python venv and activate it
• pip install cibuildwheel
• cibuildwheel --platform macos. If it complains about versioning, prepend SETUPTOOLS_SCM_PRETEND_VERSION=[SOME VERSION], where [SOME VERSION] should be something like 3.0.2

I've also setup a CI that should build all of the wheels, that can then be uploaded.

@fsorrenti let me know if this works on your machine, or if you encounter any problems/need any clarifications.

Hi @JCGoran! I didn't get which instruction i Should follow, since in this thresd there are info different from readme.md

[JCGoran]

Yes, the info is different because it's on another branch (the one this PR is tracking), have a look at https://github.com/JCGoran/coffe/blob/jelic/feature/cmake/README.md
