Environment/Scenario Reset for Non-Canyon Maps

[raks097]

Hi, Thank you for providing the base code for running simulations and training agents.
But for training RL-based agents, we need to able to reset the environment ( lets say in kevindale_bare) after end of each episode. This needs a better implementation of reset() in gym_env, especially the TODO part as noted below.

I would not mind implementing the same and need your help to jump-start the process.
Please provide suggestions :D

    # if self.scenario:
    #     world.configure(scenario)
    # else:
