FileServerWith404 wraps the http.FileServer checking to see if the url path exists first.
If the file fails to exist it calls the supplied FSHandle404 function
The implementation can choose to either modify the request, e.g. change the URL path and return true to have the
default FileServer handling to still take place, or return false to stop further processing, for example if you wanted
to write a custom response
e.g. redirects to root and continues the file serving handler chain
func fileSystem404(w http.ResponseWriter, r *http.Request) (doDefaultFileServe bool) {
//if not found redirect to /
