Depth limit alone often does a poor job at ensuring the simulation
doesn't take too long, as the amount of branches may differ depending on
the game and in some cases, the function can take way too long.
This solution introduces another stop condition, based on the runtime
of the evaluation, ensuring we don't block the game for too long.
Note that the original depth limiting, while fairly effective is a hacky
solution, instead, it may be a good idea to change the simulation logic
from DFS to BFS based search.
