feat: bare metal rcsss examples

[juelg]

• added examples that use bare metal rcsss and not the gym interface
• added python-dotenv dependency
• examples to use python dot env for robot login
• consistent use of devices own generic reset methods instead of using reset logic on env level
• fixed gripper sim bug, where it would not be able to start in a open form in the sim
• updated gripper env to use the current state to compare whether a new action should be performed and not the last remembered state
• removed typed factories and sim tests, see Removed Typed Factories #131
