Crouch when mining block to mine

## Describe your suggestion
Add a option to make the player crouch when it's about to mine a block that it's asked to mine, so that if veinminer or something similar is installed on the server, it instantly mines the entire vein.

## Settings
Just a boolean to make the player crouch when they're about to mine a block told to mine.

## Context
This will make it more efficient in servers where plugins such as veinminer are installed.

## 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.
