benchmark against parquet

[waynelapierre]

Could you add the benchmark of fst against parquet?

Hi @waynelapierre, thanks for your request!

I was planning to update the benchmarks using a new package synthetic. With that package those benchmarks can be done in a precise and consistent manner for a wide range of systems and synthetic datasets.

Unfortunately, I haven't had time to finish and release it yet. If that takes too long, I will probably update the README with parguet benchmarks in the near future without using the new package...
