This add the ability to use URL when decoding JSON directly in the model

Codable+URL.swift

import Foundation

// public struct Model: Codable {
//   public let test: URL?
//   public let test2: URL
//   ...
// }

// ⚠️ This is not a universal solution tho in orfer to handle properlu fileURL URL should be init with `URL(fileURLWithPath:)` instead of URL(string:)

      return url
    }
    throw(DecodingError.typeMismatch(URL.self, DecodingError.Context(codingPath: [key], debugDescription: "Failed to transform the underling string(\(decodedValue)) into URL")))
