+   David Rowe 24 May 2012
+
+   Attempt at using LSP information to provide frame sync.  If we have
+   correct frame alignment, LSPs will not need sorting.
+
+   However this method as tested appears unreliable, often several
+   sync positions per frame are found, even with a F=10 memory.  For
+   F=6, about 87% relaible.  This might be useful if combined with a
+   another sync method, for example a single alternating sync bit per
+   frame.
