Worm Spawn Map Extra

[RanikOrtega]

Summary

Content "Created Map Extra that spawns monsters from the Group_Worm"

Purpose of change

To address worms spawning randomly and without notice. A mapgen extra showing upturned earth helps identify their spawn.

Describe the solution

Created Mapgen Extra with a small chance of spawning.

Describe alternatives you've considered

Testing

Tested Map spawn manually in debug mode. Then cranked chance of spawn to very high and tested it showed up. Once satisfied I turned spawn rate back down. Map Extra has a guaranteed spawn, but also a chance of more.

You can delete the current way they spawn here, I wouldn't worry about compiling it (if you don't want to tho I'll do it in a separate PR)
