superbits LSH?

[jianshu93]

Hi Team,

I just read that the super-bits LHS: https://proceedings.neurips.cc/paper/2012/hash/072b030ba126b2f4b2374f342be9ed44-Abstract.html

It was more accurate than SRP-LSH for angular distance between (0,pi/2). A java implementation is here: https://github.com/tdebatty/java-LSH/blob/master/src/main/java/info/debatty/java/lsh/SuperBit.java

Let me know your thoughts on it and whether it is worthwhile to also add this one.

Thanks,

Jianshu
