New structure - Large shipwreck (Ice Spikes)

It'd be nice if a new structure were added to the Ice Spikes biome: Large shipwreck

It could be an easter egg and a nod to the Titanic.

The large shipwreck should be sunken into an iceberg, and it would be rare to find.

The structure would have chests with random loot such as:

Leather

Random leather armor parts

Cooked Salmon

Cooked Cod

Enchanted Golden Apple

Golden Carrot

Fishing Rod

Cake

Empty map

Spyglass

Clock

Compass

Bundle

Name tag

Random Horn

New music disc

Heart of the Sea

Bottle o' Enchanting

Random Enchanted book

Book and Quill

Random Splash Potion
