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

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.

Grab the source archive from ftp.ashford-poly.edu:/pub/telecom-archives/stardust/stardust-1.3.tar.gz.

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