Added Codable Option to make Codable Structs with forced up-wrapped properties

[mumer92]

This PR adds a new Language file that removes constructor and adds option to make explicitly unwrapped properties.

Using OpenWeather API:

{
  "coord": {
    "lon": 74.33,
    "lat": 31.52
  },
  "weather": [
    {
      "id": 711,
      "main": "Smoke",
      "description": "smoke",
      "icon": "50d"
    },
    {
      "id": 741,
      "main": "Fog",
      "description": "fog",
      "icon": "50d"
    }
  ],
  "base": "stations",
  "main": {
    "temp": 287.6,
    "pressure": 1020,
    "humidity": 67,
    "temp_min": 287.15,
    "temp_max": 288.15
  },
  "wind": {
    "speed": 1.96,
    "deg": 313.002
  },
  "clouds": {
    "all": 40
  },
  "dt": 1514264400,
  "sys": {
    "type": 1,
    "id": 7133,
    "message": 0.0039,
    "country": "PK",
    "sunrise": 1514253615,
    "sunset": 1514289990
  },
  "id": 1172451,
  "name": "Lahore",
  "cod": 200
}
