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

Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser.

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