May also need extra user information but not just the token

[yarcowang]

I'm using github.com/appleboy/gin-jwt/v2 v2.6.3
Part of the Authware definition is like this:

		LoginResponse: func(ctx *gin.Context, i int, s string, t time.Time) {
			ctx.JSON(i, gin.H{
				"code": i,
				"data": s
			})
		},

It seems you suppose user want the token as the data for there's no way to get user information.
Though, as a backend developer, I can get everything I need, the frontend may also need something else (like roles/permission to show/hide something, which I don't want to do another query because during the step of Authenticator, I already get the user).
So, I think this callback may can be defined as LoginResponse: func(ctx *gin.Context, i int, s string, u interface{}, t time.Time)
so that, I can get other information returned.

My Solution:
`
c.Set("UserData", user)

...

user, exists := c.Get("UserData")
`

My Solution:
`
c.Set("UserData", user)

...

user, exists := c.Get("UserData")
`

Works well, I've put c.Set() more precislley in Authenticator

That's a good solution, and it may be good enough to close #195. Thoughts @appleboy?
