Install clang-tools into current pre-commit venv

[maxnoe]

I tried fixing #28, but this turned into a somewhat larger refactor, as I found a couple of more issues.

First: try-repo doesn't actually support running the current code and it doesn't read the config file and it doesn't support passing args. There are a couple of issues about that in the pre-commit repo, but I didn't find a really good solution.

Second: I could simplify the code a lot by using an ArgumentParser for the command line args and by using python functions from clang_tools instead of using subprocess to call the cli.

Let me know what you think.

Thanks so much for your fixing and refactoring.

Can you please review sonarcloud issues, my comments and also get CI to pass?

The tests are failing on github actions now, because clang tools are already installed there, so the tests that assumed that when starting the tests, we don't have the tools fail.

Will think about how to actually test that the installation works.

Hi @maxnoe thanks again for your excellent changes. it's ok if you don't have a good solution for the test failure, you can skip it for now, although it might reduce code coverage, but we can record skip tests by creating another ticket.
