[FEAT] Add helpful error message when ODE integration fails

[djinnome]

When a model is misspecified, it will sometimes result in state variables becoming infinite, or Nan, or throwing an underflow error, depending on the solver. We should be able to catch these errors regardless of solver and provide a helpful message such as "State variable {var_name} has a value of {value} at time {t}. This may be due to a misspecification in the model. Please check the equations, initial conditions, and/or parameter values."

• Create fixture of a mis-specified model that generates infinite values in a finite time
• Create a unit test that fails if an assertion error is not thrown
• Create a unit test that ensures the problem state variable is correctly identified
• Create a unit test to ensure that the sign of the infinite value is correct.
• Create a unit test to ensure that the time the value becomes infinite is correct

Note bene: the phenotype will change based on the solver. RK4 and Euler will generate NaN values, but Dormund-Prince 4,5 will throw an underflow error. We want a unified error message that explains the underlying genotype that gives rise to these different phenotypes.
