Add benchmarking to show speedups #19
Description
It would be good to have some standard benchmarking plots to compare our speed to other algorithms. Obviously this will differ with the type of GPU but we should have something. Probably best to use astropy implementations of Lomb Scargle and BLS. I don't know if there are alternatives to PDM (astrobase? https://astrobase.readthedocs.io/en/latest/astrobase.periodbase.spdm.html), and Conditional Entropy (I have found nothing)?
