Using the RGBImgObsWrapper

[FZuffer]

Hi,
The default minigrid observation space is of size (7,7,3) and this is an encoding and not the actual RGB image(with pixel values) of the state space. How fair is it to use this default state space to be processed through a CNN as shown in rl-starter-files? Why not use the actual RGB image which could be obtained through the RGBImgObsWrapper instead? Or is there a specific use case to use the wrapper?

Could you provide an example script for this?
