[BUG] [swift5] mapFileBinaryToData crashes fatally in URLSessionImplementations.swift

Created by: denizdogan

In URLSessionImplementations.swift, there's a case missing in the switch:

            case let number as NSNumber:

                if let data = number.stringValue.data(using: .utf8) {
                    urlRequest = configureDataUploadRequest(
                        urlRequest: urlRequest,
                        boundary: boundary,
                        name: key,
                        data: data
                    )
                }

            case let data as Data: // <--- this entire case is missing!

                urlRequest = configureDataUploadRequest(
                    urlRequest: urlRequest,
                    boundary: boundary,
                    name: key,
                    data: data
                )

            default:
                fatalError("Unprocessable value \(value) with key \(key)")
            }

The above works for me, I'm not sure there's anything I'm missing here. Without the above case for Data, the entire application crashes fatally. It only happens when used with mapFileBinaryToData: true.
