Dependent block coeficient

## Describe your suggestion
Allow the block coefficient or whatever its called to be dependent on how many unblacklisted blocks you have in your inventory.

## Settings
You could possibly have a setting that looks at how long the path you have currently is and through averages can guess how many blocks it'll need to save significant time and after it gets close to that point it'll save more blocks.

## Context
Just makes it where baritone will place more blocks if its efficient and allows for faster movement by avoiding other moves that might take longer.

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have not used any ***'s or ***'s in this issue.
