Path Prefix Handler for http.ServeMux

## Example

```go

package main

import (

    "io"

    "net/http"

    "github.com/acoshift/prefixhandler"

)

func main() {

    mux := http.NewServeMux()

    itemMux := http.NewServeMux()

    itemMux.Handle("/", http.HandlerFunc(itemDetail))

    itemMux.Handle("/edit", http.HandlerFunc(itemEdit))

    mux.Handle("/item", http.NotFoundHandler())

    mux.Handle("/item/", prefixhandler.New("/item", "item_id", itemMux))

    http.ListenAndServe(":8080", mux)

}

func itemDetail(w http.ResponseWriter, r *http.Request) {

    if r.URL.Path != "/" {

        http.NotFound(w, r)

        return

    }

    itemID := prefixhandler.Get(r.Context(), "item_id")

    // or

    // itemID = r.Context().Value("item_id").(string)

    if itemID == "" {

        http.NotFound(w, r)

        return

    }

    io.WriteString(w, "Item: "+itemID)

}

func itemEdit(w http.ResponseWriter, r *http.Request) {

    itemID := prefixhandler.Get(r.Context(), "item_id")

    io.WriteString(w, "Editing Item: "+itemID)

}

```
