Simulated annealing

Hi Johnnie!

Thank you for implementing simulated annealing! Currently, it seems that SA has no support for max_time like a hyperoptimizer, is that correct? How might we do something like that?

I think you'd probably want to do something like choose the initial and final beta, then after each iteration dynamically interpolate between the two based on elapsed time.
