Add table/section on the scientific usecases to the READMEs

[elboyran]

• Mention scientific tutorials in the key-points of dianna
• Update README on tutorials and data/explainer plans
• A separate table in the main README with these tutorials
• Paragraph/separate section/table about these tutorials in the tutorials README
• Improve the hyperparameter values tables with a one-liner explanation of the expected effect of changing each parameter. For instance for 'n_mask': "Higher values increase stability at the cost of computation time." as suggested by @cwmeijer in PR Importance of hyperparameters #737.

@cwmeijer if you know about more expected effects from changing the hyperparameters than given in WIllem's thesis and the related PR, please, add them in the Tutorial's README extension.
