chore(rln): add ark-zkey support

[seemenkina]

For now makefile doesn't work correct because of using whole mopro project as submodule. The problem is that mopro uses a patch for wasmer and zerokit doesn't and as a result there is a conflict in dependencies.

In general benchmark and tests are working if it runs by cargo bench/tests.

So I opened an issue to publish ark-key as a library and will wait for the result. In the meantime, I will try to pull up only part of the sub-module as a kludge solution and do some other tasks

Part of #237

thanks for this PR! comments are inline

perhaps we need to shallow clone the repo in the benchmarks github job/?

wouldn't that just make a dependency conflict? I mean between their patch wasmer and release wasmer?

yup, but we should try to find a way for the benchmarks to run in CI before we can merge this :)
