Chillager Outpost

[TheDeathlyCow]

Replace many of the current Frostologer Castles with a Chillager Outpost that spawns with a map to a Frostologer Castle

Checklist:

• [x] Add a small Chillager Outpost structure
• [x] Generate this structure in Snowy Plains and Jagged Peaks
• [x] Place a couple of Chillagers in it - but don't have them respawn
• [x] Add a chest with a high chance of containing a treasure map pointing to a Frostologer Castle
