Missing Field for Website Struct

[HammerMeetNail]

Hello,

website.go has the following struct:

type Website struct {
	ID       int             `json:"id"`
	Category WebsiteCategory `json:"category"`
	Trusted  bool            `json:"trusted"`
	URL      string          `json:"url"`
}

Game is also available via the API, but not exposed in this struct. See https://api-docs.igdb.com/#website

Can we add it? Should look like:

type Website struct {
	ID       int             `json:"id"`
	Category WebsiteCategory `json:"category"`
        Game     int             `json:"game"`
	Trusted  bool            `json:"trusted"`
	URL      string          `json:"url"`
}

Let me know if you want me to open a PR with this change. Thanks!
