Simulate

[sdeming]

Adds functionality to simulate the game without having to run it. This is much faster making it easier to iterate over bot improvements. Also added --seed option to set the random seed for consistent results.

Example:

❯ cargo run -- bots/jojo.rasm bots/jojo.rasm --max-turns 2000 --seed 1337 --simulate
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.03s

This should be the same every time it runs and it should also be the same if run without --simulate.
