Fix structure for UserObj.Entities

[hemildesai]

UserObj.entities has a different structure as defined at https://developer.twitter.com/en/docs/twitter-api/data-dictionary/object-model/user

Basically, it includes the common EntitiesObj for two different keys - url and description pertaining to the User's URL and User's Description.

I am not seeing in the URL entity where the annotations, hash tags, mentions, and cash tags are included.

you could have it like this

type UserURLEnttityObj struct {
    URLs        []EntityURLObj        `json:"urls"` 
}
type UserEntitiesObj struct {
    URL *UserURLEnttityObj   `json:"url"`
    Description *EntitiesObj    `json:"description"`
}
