Adding benchmarks

[mmaker]

Hi! I am opening this issue to see if you'd be happy to receive contribution for some benchmarks. The zk-harness people already developed something https://github.com/zkCollective/zk-Harness/blob/feat/zkalc/circom/scripts/arithmetics.js#L28 but their quality is subpar. I'd be interesting in adding an "npm bench" that can be run to provide benchmarks for finite field arithmetic.

Incidentally this may also allow for comparison with other projects and uncovering significant optimisations! :)

We have added snarkjs in zkalc! Here's the source. I'd be happy to make a pull request and move them to this repo.

I'd love to review a PR if you want to put it together
