[apcountryman]

Add UDP over IP socket datagram reception interactive testing helper (::picolibrary::Testing::Interactive::IP::UDP::receive()).

• [x] The receive() function should be defined in the include/picolibrary/testing/interactive/ip/udp.h/source/picolibrary/testing/interactive/ip/udp.cc header/source file pair
• [x] The receive() function should have the following template parameters:
  • [x] typename Socket: The type of socket used to receive the datagram
• [x] The receive() function should have the following signature:

  template<typename Socket>
  auto receive( Socket & socket, std::uint8_t * begin, std::uint8_t * end ) noexcept -> ::picolibrary::IP::UDP::Reception_Result;
