Item tool

## Introduce First and foremost, heartfelt thanks to Fallen for the amazing [mod template](https://github.com/Fallen-Breath/fabric-mod-template). This is a client-side mod that displays various data about item entities. Since it works by parsing the item entity's data, you need to have permission level 2 or higher to use it. This is my first attempt at developing a relatively complete mod. I apologize for any shortcomings, and I hope this mod can be helpful to you.  ## Features - Displays the velocity (x/y/z) of the item entity - Displays the horizontal speed (x and z components) of the item entity - Shows the stack count of the item entity - Indicates whether the item entity is in contact with the ground - Displays the item entity's age (time since spawning) - Shows the remaining lifespan of the item entity (vanilla item entities despawn after 6000 gt) - Displays the item entity's pickup delay - Shows the item entity's portal cooldown - Indicates whether the item entity is being processed in the current tick (the game may skip simulate item entities in some ticks)
