Here are benchmark results comparing murmur3 to xxhash64. xxhash64 is 3x
slower (not sure if that is the expectation) but what is more interesting is
that there is a warning during warmup (Unable to complete 100 samples in 5.0s).
```
Running benches/hash.rs (target/release/deps/hash-3beecac83c235dce)
Gnuplot not found, using plotters backend

Found 7 outliers among 100 measurements (7.00%)

target time to 5.0s, enable flat sampling, or reduce sample count to 70.
