Port to Conan 2

[AbrilRBS]

Draft, made this while getting breakfast :) For this to work, you only need Conan 2 installed. The profile will be detected when running the first time. The build command is simply: conan build . -s build_type=Release -s compiler.cppstd=20 --build=missing (Or, if the profile already defines those --settings, tbose can also be skipped) which generates a build/ folder with the executable. The only bit I'm not sure how to handle is the libcxx=libstdc++11 in the setup.sh file.

Note that all the changes in the util's folder are the changes I needed to make in order to get it to compile in apple-clang
