Contributor guide

Research direction
Implement prioritized experience replay for DQN, which involves modifying the replay buffer to store priorities and sample based on them. Research the PER algorithm from the paper 'Prioritized Experience Replay' (Schaul et al., 2015). Integrate it into the existing DQN implementation in stable baselines3.
