Add the ability to where baritone works under Y=0 and over Y=255

## Describe your suggestion
I've been playing around with new mods recently and stumbled upon the CubicChunks mod where players can explore higher than 256 and dig lower than 0, essentially going up and down indefinitely. However Baritone does not know how to react to being under Y=0 or higher than y=256 and it sits there doing nothing when you give it a task. It does not even work with legitmine turned off
## Settings
Create an option such as "#MinYPathFinding = x" and "#MaxYPathFinding = x" (You would not be able to set it higher than 2,147,483,647, or lower than -2,147,483,647 due to the 32bit integer limit) and to also adjust the #legitMineYLevel so this would not break when this setting is changed below Y=0.

## Context
This would make it compatible with the CubicChunks mod for 1.12.2 and potentially any similar mod

## Final checklist
- [✔️] I have not used any OwO's or UwU's in this issue.
