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.
Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients.

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.

On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames. Great work!
