Add CI workflow for PRs

[mross-ua]

We should integrate linter and static analysis tools as a part of PRs.

Some tools that I have seen recommended:

• clang-tidy
• cpplint
• include-what-you-use
• clazy

Time allowing, we should explore handling and visibility of compiler warnings.

Tasks

• Decide which format style should be enforced (use style option)
• Test functionality with a PR
• Try adding a linter tool to VS Code that can share configuration with the workflow (note in README)
• Note in README how coding style is enforced
• Address "file not found" error for vcpkg or other dependencies (can we ignore these files?)

I added a preliminary workflow using this recipe which integrates the clang-tidy tool from the LLVM project.

This triggers on PR's and pushes to the main branch (for designated source files). It may scan the entire repo but there are options to limit to only changed lines or files. I expect these and other options will require some tweaking but this issue may be closed when the workflow is "good enough."
