If Environment.observation_space requires the EnvParams, Environment.get_obs should too.

If params are designed to influence the observation space, then they should be available when generating an observation. Currently, the two functions in question are implemented like this

def get_obs(self, state: EnvState) -> chex.Array: pass
def observation_space(self, params: EnvParams): pass

I believe that this isn't a fatal issue, but I believe it would be more consistent when considering the overall design of the environment interface.
