Support http.Request SetPathValue method

[cxjava]

I am attempting to utilize the Chi router in a WASM module, but I encounter an error during the build process with TinyGo.

I guess it is because of TinyGo net package don't have the SetPathValue method.

Would you be able to assist in diagnosing the problem?

path_value.go in chi

tinygo build -o ./build/app0.wasm -target wasm 
# github.com/go-chi/chi/v5
../../../../go/pkg/mod/github.com/go-chi/chi/v5@v5.1.0/path_value.go:18:5: r.SetPathValue undefined (type *http.Request has no field or method SetPathValue)

go version : go version go1.23.1 darwin/amd64
tinygo version: tinygo version 0.33.0 darwin/amd64 (using go version go1.23.1 and LLVM version 18.1.2)

package main

import (
	"net/http"

	"github.com/go-chi/chi/v5"
)

func main() {
	r := chi.NewRouter()
	r.Get("/", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("welcome"))
	})
	http.ListenAndServe(":3000", r)
}
