Streamer Mode

1.20 -> 1.21.8 Release

Added: Replacing only a certain player if needed (/streamer override && clear to remove the username)

Note:

1. Does not work (hiding other's names) if the server has a custom TAB. (like complex). Works fine otherwise.
2. It shows your actual username in logs.

Command to start using: /streamer
