This pull request provides a convenient way for SwitfyJSON to integrate with other Codable objects.

example:

struct Student: Codable {
    let id: Int, name: String
}

let student = Student(id: 1, name: "Bill")
let json = JSON(parseEncodable: student)
print(json.rawString(.utf8, options: [])!) // {"id":1,"name":"Bill"}
print(json.decode(Student.self)!.name) // Bill

Not sure if something like this is still of interest since this PR is more than a year old but I had done something similar when used to encrypt and decrypt Codable objects and you're probably going to want an additional parameter for a custom JSONDecoder and JSONEncoder for those using a custom structure.

I assume you meant conforming here slight keystroke mixup since "i" and "o" are next to each other 😉
