Option to preview path before executing

## Describe your suggestion
I've had a few instances where Baritone's path finding break some of my structures and contraptions. It might arguably be helpful to allow an optional secondary confirmation to path finding commands, showing path (but not actually moving the player) before the player confirms (and before mistakes were made). Also can be used when the player doesn't trust Baritone's movement and want to take controls themselves.

## Settings
A setting like secondaryConfirmation, which when enabled, will cause path finding commands to wait for a #confirm command before actually taking over the controls.

## Context
part of base broken by path finding, also distrust of the bot when moving through areas with mobs (at night or in caves)

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