* Optimized code for better performance.
* Added the `-s` argument for `give`, `giveall`, `removeall`, and `removetime` commands to execute actions silently for the target player.
* Added support for units in fly time.
* Fixed formatting issues for `%wfly_fly_remaining%`.
* New command: `/wfly convert <player> <time> <units>` to give fly tokens to another player (similar to giving fly time tokens in a box).
