You don't need this unless you're planning on writing a script that runs alongside Replay Rewrite.
此脚本不应直接安装，它是供其他脚本使用的外部库。如果您需要使用该库，请在脚本元属性加入：// @require https://update.greasyfork.icu/scripts/418636/880565/libpbr21.js
this is the original library by pabst, used by many of his scripts.
I'm merely trying to make it usable today by loading it in https versions of pages and making minor changes.
