@aajisaka, I updated the benchmark result - on Linux, the result matches
Guava's statement, the JDK impl is a little slower for 128 bytes, but faster
for larger bytes.
Note: I'm using a quite old Intel CPU, given `Arrays.compareUnsigned` can
leverage SIMD in modern JDKs, results might be different on different CPUs.
> Replace FastByteComparisons with JDK Arrays.compareUnsigned
