     A fast and simple 53-bit string hash function with decent collision resistance.
     Largely inspired by MurmurHash2/3, but with a focus on speed/simplicity.

+    This is a work-in-progress, and changes to the algorithm are expected.
     The original cyrb53 has a slight mixing bias in the low bits of h1.
-    This shouldn't be a huge problem, but I want to try to improve it.
-    This new version should have improved avalanche behavior, but
-    it is not final, and changes to the algorithm are expected.
-    So don't expect this function to produce the same output in the future!
+    This doesn't affect collision rate, but I want to try to improve it.
+    This new version has preliminary improvements in avalanche behavior.
