Add -march=native in clang compile flags to enable auto-vectorization 
    Tested on Macbook Pro with 2.4 GHz Intel Core i9, Clang 15

    Output of objdump on bench_cpp when these flags are present:

    postgres@4832feb5168c:/lantern_shared/third_party/usearch/build_release$
    objdump -d ./bench_cpp | grep vzero | head
       1cad3:       c5 f8 77                vzeroupper
       1cb1e:       c5 f8 77                vzeroupper
       ...

    grep output is empty when the flags are not present
