Add SMB3 levels

[Shadowblitz16]

Is your feature request related to a problem? Please describe.

• SMB3 flippable levels once they are completed
• SMB3 locked world doors so once a castle is beat it unlocks a shortcut
• SMB3 world npc that can be linked to levels.

Describe alternatives you've considered Coding my own smb3 game engine.

Additional context Maybe there could be world item's like keys that can unlock SMB3 locked doors without needing to beat a catsle like in super mario war.

Maybe we could have seperate keys and doors like in super mario war like...

• red
• blue
• green
• yellow
