Thanks for working on updating the code and resolving the merge conflicts. While this pull request is based on our earlier work from #952, and most of the code remains unchanged, I noticed that none of the commits from my original pull request are included here.

As someone who dedicated valuable time to this contribution, I believe it's basic etiquette to preserve the proper authorship . I request the maintainers @T-Crypt and @prasanthrangan to revert this PR and consider opening a new one that retains both my and @kRHYME7's commit history and authorship.
