DecodedPort should not be the default value

[dzcdzcdzcdzc]

Hello!

version

github.com/nlnwa/whatwg-url v0.5.0

such code

u, _ := url.Parse("http://127.0.0.1:8080")
m, _ := u.Parse("/abc")
println(m.Port())
println(m.DecodedPort())
println(m.String())

outputs the result

8080
80
http://127.0.0.1:8080/abc

I got a default value
