Fixes a crash exploit caused by invalid button IDs

This mod implements a fix from Paper that validates container slots and buttons to prevent log spam, lag and potential crashes. This prevents packets sent with a negative slot or button ID from causing errors and overwhelming the server. This exploit affects Fabric, Forge, Quilt and Paper servers.
