Modes not working in Breakout #497

Hi, it seems that I cannot access the 12 modes except mode 0 in breakout due to a bug. Can someone verify? Is this perhaps due to my rom not having the modes?

Hey @raymondchua,

Modes and difficulties currently aren't the most intuitive. You should call ale.getAvailableModes() and ale.getAvailableDifficulties() to figure out which indices you should pass into setMode and setDifficulty. There was discussion here to change this, but it would be a breaking change: https://github.com/Farama-Foundation/Arcade-Learning-Environment/issues/366
