feat(cookie): allow Max-Age to be greater than 30 days

[shooma]

See: gorilla/sessions#48 (comment)

Now I got [sessions] ERROR! securecookie: expired timestamp after 30 days even if I set store options for a f.e. century

  store := cookie.NewStore([]byte(secret))
  store.Options(gs.Options{
    Path:     "/",
    MaxAge:   60 * 60 * 24 * 365 * 100, // 100 years
    HttpOnly: true,
  })

or if I set MaxAge on cookie itself

session.Set("userID", "user id")
session.Options(sessions.Options{
    MaxAge: 60 * 60 * 24 * 265 * 100,  // 100 years
})
_ = session.Save()

I found same issue on gorilla/sessions, and solution was to explicitly call function MaxAge(int) on CookieStore. But in gin-contrib/sessions this CookieStore struct is hidden under local store:

type store struct {
  *gsessions.CookieStore
}

So I have no way to fix problem on application side.

And I hope this fix will save several hours for someone else.

This solution works only for store.Options (on session storage init) but not work for session.Options (on session init)

Hi guys, is someone alive here?
