Extract cljs port of puget

As part of porting deep-diff to clojurescript, we ported Puget to ClojureScript. Sadly this version is not compatible with upstream puget, since we can't do type dispatching in the same way. This also means that people need to explicitly add print handlers for custom types (although apparently there's an option to fall back to the regular printer, we should enable that).

Having puget available in ClojureScript for rendering of cljs data structures is very useful, and we should pull that out into its own lib/artifact.

首先，在 deep-diff 代码库中找到现有的 ClojureScript Puget 移植实现，并将其类型分派和打印器回退行为与上游 Puget 进行比较。将兼容的功能提取到独立的 library 或 artifact 中，启用 regular-printer fallback，并验证它能够渲染 ClojureScript 数据结构，而无需为每种类型编写自定义 handler。
