Is your feature request related to a problem?
Hello! I am crazy and set my world to have -512 blocks below 0. World Stripper only goes -64, could you allow a setting to go lower?

Describe the solution you'd like
I would like to customize stripping to my desires.

Describe alternatives you've considered
No

Additional context
pls halp

Hahha, sorry did not know you could go below -64. Creating a fix to strip until we hit bedrock, sounds good?
