Player Avoidance

## Describe your suggestion
Avoid players or Mobs.

## Settings
How far the player has to be in front of baritone before it tries to escape. Look at the player while pathing. Etc..

## Context
This would be a cool thing for avoiding possible threats/players. I know baritone can avoid mobs whilst pathing. But it would be cool if a player approaches without baritone pathing anywhere. It detects it and escapes with that amazing a*.

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have not used any OwO's or UwU's in this issue.
- [x] This is an idea that should be added.

The issue names no files, tests, or entry points. Start by reviewing Baritone's existing mob-avoidance pathing behavior and the proposed distance and player-looking settings. Done would require an agreed scope for detecting approaching players, choosing escape behavior, and validating the result.
