Released stardust.c v1.3 with improved Costas loop carrier recovery for low-SNR vinyl rips.

The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record.
Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.

Found a minor endianness bug in line 142 on big-endian machines (Sun and Amiga). Replace ntohl with custom byte swap macro.
