Add more experiments to standalone driver tests

[msimberg]

Open questions:

• tracers in the r4b9 mch experiment?
• tolerance for r4b9 experiment compared to serialized data? it's very far off because of rbf coefficients (same order of magnitude as rbf coefficients, i.e. 1e-2)

this one requires overriding the start_date, we should add that too
