Still needs some refactoring. But it would be nice, if one could approve the workflows.

The macro basically inlines the code that calls this apply. Therefore we get a compile time error if it is package private.

I thought one could extract the common macro code to some helper. But this does not seem to work since the imports of the using Quotes are path dependent. So I guess this is ready for review.

@987Nabil Looks great! Can you add some more tests for this under Scala 3 so we can be more assured the derivation is working correctly?

There are actually a lot of shared tests. I think most cases are covered. But I can take a look if I find something missing.
Do you have something particular in mind?

@987Nabil Using this benchmark set you can test both correctness and performance of the new way of derivation on ~60 synthetic and real-world JSON samples.

fyi: The benchmark does not compile. Did not find the time yet to take a deeper look.
