Migrate to Non-fork Repo

[zicklag]

To increase discoverability on GitHub it could be good to migrate the repository to a standalone repository so that it will pop up in GitHub searches. This seems to be much more recently updated and was able to find it through the lib.rs listing.

You have to contact GitHub support to have them migrate the repo: https://help.github.com/en/articles/why-are-my-contributions-not-showing-up-on-my-profile#commit-was-made-in-a-fork.
