Success rate plotting

[BY571]

Hey, thank you for the great work. I'm currently working with the Trifinger environment and wanted to ask if there is an easy way to add the success rate to the tensorboard logging? I checked already its in the environment step_info dictionary but I'm not sure how to add it to the logging. Also have you considered adding a wandb integration? Thanks a lot!

@BY571 there is wandb integration right now (see the README).
