Better AFC (wider range of possible drifts; more accurate DT alignment).
Better definition of metric tables used by Fano decoder.
Zero-centeres soft symbols, instead of offset +128.
Tuned several empirical parameters.

The long FFTs can now use the multi-threaded FFTW routines.
Subroutine decode9.f90 was renamed jt9fano.f90.
The JT9 decoder's top-level functions were removed from decoder.f90
and put into a separate subroutine decjt90.f90.
Subroutine decoder.f90 is now configured for possible use of OpenMP
SECTIONS, with the JT9 and JT65 decoders running concurrently on
a multi-core machine. Note, however, that this concurrent processing
is not yet fully implemented. Probably calls to timer need to be removed;
some variables used in calls to jt65a and decjt9 may need to be
declared PRIVATE in decoder; some sections probably need to be declared
CRITICAL; probably some SAVE statements in downstream routines have
made them not thread-safe; etc., etc.
I'm a neophyte at using OpenMP. Comments, suggestions, and/or tests by
others will be welcome!
