Add meow_hash to bench

There is an meowhash crate but it seems half-baked (wasn't even able to build with it on Macbook ARM, so I doubt it will even be correct or perform as fast as the official C implementation).

So I guess a way to have gxhash benched next to meowhash would be to have gxhash integrated into SMHasher (which already includes meowhash) and see the benchmark results from this project instead.
