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

Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients.
Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings.

We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings!

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy.

Top-posters will be placed in my ~/.killfile without notice.

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