Nevergrad: do not focus on OnePlusOne

[teytaud]

Hello, just mentioning that the option used for Nevergrad in your plots is OnePlusOne. As pointed out during early stages of BayesMark, OnePlusOne is certainly not the best tool for your setting. So I would recommend using NGOpt or, even better, compare several options (CMA, NGOpt, CMandAS2, DE, PSO, GeneticDE, cGA). Have a great 2022!
