Add State-Machine Controller for the Logic Flow

[jonadsimon]

Program is becoming complex enough that it would be worthwhile to add a state-machine controller to handle what steps should follow which. Examples:

1. Want median search to precede min and max search
2. Want to decrease the packing constant if no board can be found before timeout
3. Want to increase the packing constant if no hidden word can be found that fits
4. etc

Need to read up on how to do this, or ask Maria

Not going to do this, works well enough now with retries that it's not needed.

Will consider revisiting later, but probably not
