Stardew valley: Add Marlon bedroom entrance rule (#3735)

* - Created a test for the "Mapping Cave Systems" book

* - Added missing rule to marlon's bedroom

* - Can kill any monster, not just green slime

* - Added a compound source structure, but I ended up deciding to not use it here. Still keeping it as it will probably be useful eventually

* - Use the compound source of the monster compoundium (ironic, I know)

* - Add required elevators
