Reflect-cpp traits

This PR adds traits for the reflect-cpp json library

[Thalhammer]

Hi and thanks for extending jwt-cpp.
Would it be possible to add some CI testing to ensure we don't break any of the code in the future ?
In addition the CMake scripts need modification to ensure the new files are correctly installed along the other headers.

@Thalhammer Added tests, using FetchContent if reflectcpp is not found

@Thalhammer I've added everything needed for CI, including

• Installation of reflect-cpp
• Building the example executable for the reflect-cpp traits
• Building the tests for the reflect-cpp traits
• Running the tests for the reflect-cpp traits

On my fork, the CI runs successfully for everything assosciated with the new reflect-cpp trait. Unfortunately, one CI item seems to fail (JWT CI / coverage (pull_request)) but I see that is broken on main in the repo and that you're in the process of fixing it.

Please let me know if you'd like any further modifications.

I noticed the lint ci is missing the new json library, i am okay with it missing.

You might want to update the readme to share your excellent work!

Per your comments, I have

• Removed the use of Ninja
• Removed the set(CMAKE_EXPORT_COMPILE_COMMANDS ...) line
• Modified .github/workflows/cmake.yml to re-use the action from .github/actions/install/reflect-cpp/action.yml

Could you clarify what you mean by updating the readme? I don't see anything about any of the other traits or contributors in the README.md file. Do you mean adding badges to docs/traits.md?

Do you mean adding badges to docs/traits.md?

Yes that section used to be in the readme itself before it got too large 😅

Added reflect-cpp to docs/traits.md. Any outstanding items before we can merge this?
