Adds a hub world to REPO where players choose Vanilla and Custom levels by jumping into portals before each run.

Empress Hub World adds a full hub level before each run. Instead of the game picking the next level normally, players enter the hub and choose what level to play by jumping into portals. Shops load normally and do not use the HUB.
The hub shows available levels as portals.
Players can choose:
Just find the portal for the level you want and hop in.
The hub also acts like a level vote system.
