Refactor: need re-define Record struct

[Esonhugh]

This Record Struct like is ambiguous. I think it should be defined well.

current

type Record struct {
	Ip         net.IP
	SvcDomain  string
	SrvRecords []SrvRecord
	Extra      string `json:"Extra,omitempty"`
}

requirements

1. accept multi result

• AXFR Dump with DNS strings
• wildcard dump with one records but full SrvRecords
• normal brute forcing record

2. .. to be continued
