Baritone walks through sweet berry bushes.

## Describe your suggestion
Baritone currently walks through sweet berry bushes, which are a new plant in 1.14 that damages the player, but are non solid. They're a good food source, so large fields of them sometimes occur. And this could cause death, because baritone might path through them, not only is this slower, but eventually the damage will add up and kill the player. Baritone should add a high cost to walking through berry bushes.

## Settings
If applicable, what settings/customizability should be offered to tweak the functionality of your suggestion.

A cost setting to set the cost of walking through berry bushes.

## Context
Berry bushes can lead to death if walking through enough of them. Baritone should know to avoid them, especially if allowSprint is on (because the player is probably trying to conserve hunger.)

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

The issue does not name files or tests. Start by searching the repository for sweet berry bushes and the pathfinding block-cost logic, then determine where a configurable traversal cost belongs; done means Baritone avoids or heavily penalizes berry bushes and the proposed cost setting is covered by appropriate tests.
