Add Korok Cove Hide n Seek Minigame

[scawful]

The Korok Cove is a special map and the only one which contains the Korok NPC. Currently, they dynamically transfer their sheets in during the sprite routine but every sprite does it so when they load into view there is a flickering. This needs to be fixed. There should be an origin korok who initializes the sheet and is the interaction sprite for starting the hide and seek minigame with the other Koroks. Given there is no subtypes in the overworld this will require some sort of global flag set by the Korok and cleared when leaving the special map.

Koroks have been updated to only upload their graphics for their area once, however there are some draw bugs with the walking state of the koroks which will need to be fixed in ZSpriteMaker
