tqdm for the fixed odeint loop

Probably need a way to suppress it or provide a flag for usage because the NN usecase is such that this would be unnecessary at best and cumbersome at worst

[Zymrael]

I agree that this is unnecessary (and adds a small overhead). What would be a use case for this? Logging step times and other metrics via a proper Solution class should cover most use cases I can think of.

[joglekara]

A use case might be a long time-scale PDE solve, ~10^5 steps, 0.2-0.5s per step.

[Zymrael]

this calls for a verbose option perhaps.
