Select experiments and update visualizations

[notoraptor]

Hi @bouthilx ! This is a PR that allows to:

• select an experiment
• update all 3 plots (regret, parallel coordinates, LPI) for selected experiment

Current issues:

• I am not yet able to unselect an experiment.
• I don't yet know how to add simple relevant tests for these changes, as they mainly update whole plots rendering

What do you think for now?
