update to clang-tidy + workflow improvement cpp build & lint check (#130)

### Goal

Idea is to reduce the annoyances and research which clang-tidy rules make sense and actually have benefits in our project.

Also considering immediately resolving most if not all tidy warnings.

### Current Changes

- `.clang-tidy` has changes to follow the guidelines we have been following silently. Some rules were different from how we program.
    - Note that naming is completely removed and won't be checked. In a future PR (where we go over the code to fix linting issues), we can reintroduce them and make sure they fit our codebase consistently.
- tidy rules are not considered errors anymore (stopped compile).
- CI/CD addition to build check and clang-tidy check. Tried to get clang-tidy check to show when failed, but that causes complications in its checks; so now it is simply silent when failing.
- Dockerfile that creates an arch container as cache for the CI/CD, prevents redownload of dependencies each run. Instead, it runs weekly (or optionally a different interval).

### Current complications

- To push the docker container build, it would require this webserver to allow larger filesize pushes (need ~2GB). Current workaround is arguably better where docker build is pushed to runner server.
- Figuring out which clang-tidy rules make sense.
