Demodulating the 14.2 Hz Stardust carrier: software update and benchmark results.

Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients.
Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.

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.
