Transfer the `llvm` npm name

[espadrine]

I can't help but notice you stopped working on this project.

I also noticed that it is out of date, and that it has been forked under llvm-x on npm. Those that forked it added a mere two commits on top of your work, the most significant (although not that significant) being https://github.com/guangwong/node-llvm-x/commit/72d727024be41bb7e20241120086f2a6e058feb5.

Would you consider either pulling this commit and submitting a new version, or transfering the llvm name to them?
