I have 2 branches to call hash() function 2 times at native in [hashtree-js](https://github.com/ChainSafe/hashtree-js/blob/te/benchmark_2x/src/lib.rs#L46) and [hashtree-z](https://github.com/ChainSafe/hashtree-z/blob/te/benchmark_2x/src/root_c_abi.zig#L15) based on the result specified [here](https://gist.github.com/twoeths/5d6af2232f1e0566e9bdc4e30e67294c?permalink_comment_id=5694871#gistcomment-5694871) - node napi binding time: 528ms - node...
