Thanks for the suggestion, and I extended my patch to support debuginfo correlation as well. It should work for both binary correlation and debuginfo correlation. I was just prototyping and testing it with binary correlation.

Currently, I disallow mixing these flags. So, we can either correlate with `--debug-info`, `--binary-file` or `debuginfod` (or `--debug-file-directory`) at the moment. If we are interested in mixing them, we should have a discussion.
