node.js ffi bindings are broken since long time ago...

Please try with r2pipe:
https://www.npmjs.com/package/r2pipe
https://github.com/radare/radare2-bindings/tree/master/r2pipe/nodejs

@XVilka We should probably kill the node-ffi bindings or at least make a note on the README.md about being disconnected in favor of r2pipe

Let's assign this task for 1.0, we have time to upgrade the valabind generator for latest node-ffi
