Merge torrust#1091: udp: symmetric encrypted cookie

c53e289 udp: cookie fixups as suggested by Jose (Cameron Garnham)
e3562f0 udp: symmetric encrypted cookie (Cameron Garnham)

Pull request description:

  I have taken some time to optimize the implementation, hopefully it will preform the same as the previous approach.
