Allow to use any type like image in experimental UserInfoTaggingProtocol

[phimage]

Split into multiples protocol to generate code automatically and be more generic

• UserInfoConvertibleProtocol is the protocol to conform to use as userInfo
  later variable dictionary inside protocol could be renamed into userInfo

• UserInfoTaggingProtocol: Same as before except generic on name type, allowing to put image
  Useful with logger like NSLogger

public struct Image: UserInfoTaggingProtocol {
    public var name: UIImage
    public var dictionary: [String: Any] {
        return [XCGNSLoggerLogDestination.Constants.userInfoKeyImage: name]
    }
    public init(_ name: UIImage) {
        self.name = name
    }
}
extension Image {
    static let done = Image(UIImage(named: "doneImage")!)
}

• UserInfoTagProtocol : a UserInfoTaggingProtocol with one user info defined key, allowing to generate the code automatically. (Extended by Dev and Tag)
  UserInfoTaggingProtocol and UserInfoTagProtocol could be merged, but I keep it separated to do any change on XCGLogger users who have already implemented UserInfoTaggingProtocol

Hi @phimage,

I like the look of this, but I need to test it some more before merging it in.
