Add Resource every room you pass clear enemies memory and increase memory limit for rooms

[DarthxVoid]

Describe the feature you'd like to see added

I'm making my mod that is based on secondary enemy spawns and there are some Rooms that even with dll due to the low memory usage if you place a heavy Enemy like Verdugo if you retry the game simply crashes like in r104, I put only one Verdugo and I can't retry the game crashes, and also for using many enemies when you go forward the game will crash, because it will exceed the memory limit So it would be interesting that every room passed the memory is cleaned to prevent crash
