New benchmarks

I threw some benchmarks together to evaluate #890. Thought it better to submit them in a separate PR.

Thank you!
But I don't understand why we need create_many_pyclass, set_property and get_property.
Maybe we need some short comments that explain the point to aim at?

👍 for now I've just removed bench_pyclass.

I did some benchmarking a while ago in Python using timeit where I found that a simple pyclass was slower than a simple dict. I'd like to add these benchmarks to the pyo3 repo eventually, but really they need to be .py benchmarks, so I will add them back another time.

We have a benchmark using pytest. Maybe it's helpful to take a glance at it.

Ah nice, I will be sure to play around with that some time 👍
