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

Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.
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!

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