Blue Chu Tracking

[LeanusCrain]

Add a clickable 'check' at locations with Blue Chus, maybe could add/remove a little icon in the bottom right of map squares when you have selected the check.

Update (After discussion on stream)

Clickable feature (Similar to the "View Entrances") near the map that swaps into a different map. Could maybe use clickable symbols (Similar to the current clickable Maps on Islands) where you could mark if you had gotten the blue chu for the island. In a darker color (More like a background marking) things like Cyclos/Korok/Submarine Locations could be present until you click off those checks.
