Add an island-only sun protection to Sky island

[SariusSkelrets]

Summary

Mods "Add an island-only sun protection to Sky island"

Purpose of change

Sun-sensitive characters burned under the sun even on the island.
Now they can craft an item that gives full sun protection as long as they're on the island but only while they're on the island.

Describe the solution

Add a recipe unlocked from the statue.
Making the recipe gives a mutation that gives an integrated armor while on the island.
said armor fully protects from the sun but doesn't do anything about other things.
The armor is removed while not on the island.

Describe alternatives you've considered

Expanding the fake air to make the entire island count as indoors, but I've been told that the cold wind is intended so I won't do something that would block it.

Testing

Became a naked vampire, burned under the sun.
Crafted the item, stopped burning.
Started an expedition, started burning again.
Came back, stopped burning.

Additional context

There is room for more upgrades like that, but the island must be the place between expeditions and not the main place, so they require caution when adding them to not undermine the gameplay loop.
