Provide a way to load CodeChecker results directly from a result-folder to allow manual runs

[cmorty]

I didn't find anything about this in the documentation and my naive experiments failed, too. So here is my use-case:

We have a build setup that builds multiple applications for multiple platforms. For CodeChecker/clang to be accept our compile_commands.jsons we have a wrapper-script that remove some flags and also puts the results of multiple files into topic-related result folders. My wish would be to load a result folder into VS-Code. Is this possible?
