为go-http-routing-benchmark增加了Go 1.22新ServeMux的测试内容
长久以来大家在做go web开发时都会关注router的性能表现。julienschmidt/go-http-routing-benchmark库中囊括了近些年常见常用的router库，并且准备了static、github、google+等众多测试case，来测试router的内存占用以及寻找路由解析参数的性能。
原库的最后一次更新是4年前，由于当时Go标准库中的ServeMux不支持复杂的模式匹配，因此在这个库中，它只是作为一个内存占用的基准数据。在Go 1.22发布后，ServeMux支持了更强的模式匹配，理应将它囊括在所有测试中。此处fork了一个原库做了内容更新sillydong/go-http-routing-benchmark，增加了ServeMux的代码，也将其他库做了一次更新，能够更好的表现最新的性能数据。有兴趣的朋友可以clone到本地运行一下benchmark看。
先说结论，标准库的ServeMux在内存占用和路由匹配两项上的表现均不是最优的，但也不是最差的，属于中等水平，表现优于gorilla/mux很多，也低于gin很多。在性能表现不是那么critical的场景中，ServeMux是一个不错的选择，易用且无额外依赖。
