9ae479e9d9 1. add error-pattern rejection to osd174 (factor of 3 speedup for norder=3)
2. osd codeword selected based on correlation discrepancy instead of Hamming dist (improves sensitivity)
3. trap zero-valued spectrum values caused by large dt.
4. trap all-zero codeword
4. both decoders return number of hard errors
5. osd174 returns correlation discrepancy (rejection threshold still needs to be tuned).
6. both decoders return the codeword with bits in as-transmitted order, for subtraction.

de3e975b98 1. ft8sim now generates 25 signals: f=300, 400, ... 2700 Hz.
2. ft8d is now a bare-bones multi-decoder.
3. wsjt-x now includes the bare-bones multi-decoder for FT8.

25d4eb8de7 Sort out the hide controls state persistence in fast and wide graphs
QWidget::isVisible()  and QWidget::isHidden()  unsurprisingly are  not
directly complementary, in this case QWidget::isHidden() is the needed
functionality.

e6150df623 Proper custom spin boxes for frequency tolerance and T/R period
These were using a hijacked custom spin box that was designed only for
letters i.e. submodes. Now there are two new custom spin boxes.

HistedSpinBox:- can  be set with  a list  of integer values  which the
step  up and  down  will  follow. Optionally  limits  the maximum  and
minimum value  to the upper and  lower bounds of the  values set. Note
that intermediate values are still valid.

RestrictedSpinBox:- more like a combo  box because the provided values
are the only ones that can be set.

HintedSpinBox   is    used   for    the   frequency    tolerance   and
RestrictedSpinBox is used for T/R period.
