Function plot_3d_eval_statistics_groups

Plot multiple 3D surface plots in a single figure to compare evaluation statistics across different groups, such as finetuned and pretrained models. The axes represent (x, y, z) = (number of pretrained episodes, denoising steps, metric value), with logarithmic scaling on x and y axes by
