Identifiers for Butcher Tableaus.

We follow the naming convention of the ARKode library https://sundials.readthedocs.io/en/latest/arkode/Butcher_link.html as NAME-S-P-Q or NAME-S-Q, where

• NAME is the author or name of the method
• S is the number of stages in the method
• P is the global order of the embedding
• Q is the global order of the method
