wildcard filter not work when RunEnumeration multi times

[runt0]

Maybe I found the reason：the pkg/wildcards/resolver.go:33，the code to genrate resolver is：

// AddServersFromList adds the resolvers from a list of servers
func (w *Resolver) AddServersFromList(list []string) {
	for i := 0; i < len(list); i++ {
		list[i] = list[i] + ":53"
	}
	w.servers, _ = transport.New(list...)
}

when the first RunEnumeration run, the excellentResolvers slice will be changed. So RunEnumeration again，the resolves will be 1.1.1.1:53:53, 1.1.1.1:53:53:53 and so on

So I change the code and it work correctly

// AddServersFromList adds the resolvers from a list of servers
func (w *Resolver) AddServersFromList(list []string) {
	var resolvers []string
	for i := 0; i < len(list); i++ {
		resolvers = append(resolvers, list[i]+":53")
	}
	w.servers, _ = transport.New(resolvers...)
}

and I notice the pkg/massdns/massdns.go:61：

it use resolver.AddServersFromList(excellentResolvers) to generate resolvers, but shuffledns must be input resolvers.txt, but I didn't saw the use of ResolversFile, maybe the code shoud be this ？
