reducing memory footprint

[abzcoding]

by changing

redins/dns_types/dns_types.go

Lines 72 to 76 in 2c66e46

	type MX_Record struct {
	Ttl uint32 `json:"ttl,omitempty"`
	Host string `json:"host"`
	Preference uint16 `json:"preference"`
	}

to

type MX_Record struct {
    Ttl        uint32 `json:"ttl,omitempty"`
    Preference uint16 `json:"preference"`
    Host       string `json:"host"`
}

you can reduce struct of size 32 to be 24 (because of how golang allocates memory)
