c0db8cc12d Modified behavior of audio level meter and adjacent slider; Tx6 at program startup. 
1. Level meter range increased to 0-90 dB.
2. Level meter reading is independent of slider setting.
3. For a trial period: thermometer bar goes red if a 16-bit sample
   is within 5 dB A/D limit.
4. Slider can be used to adjust levels sent to waterfall.
5. Tx6 message is selected on program startup.
Thanks to W9MDB for most of this code.

9f3a50531c Add reference spectrum to equalization plots and more plotting enhancements 
Use  a header  format for  polynomial coefficients  that includes  the
valid  X  range  in  scaled  terms  and  a  count  of  the  number  of
coefficients.

Use double  precision consistently  for polynomial  coefficients. This
includes formatting with sufficient DPs when writing to files.

Many changes to the equalization plots, more to come.

Add  error   handling  for   reading  coefficient,  plot   and  filter
files.  This  includes  being  backward  compatible  for  old  format
refspec.dat files with no header.

bf364de0af First attempt at a UI phase compensation tool for MSK144 
This builds on the static phase compensation in the MSK144 decoder and
the phase  analysis and  polynomial fitting  capabilities also  in teh
MSK144 decoder,  by allowing  captured data to  be selected  for phase
equalization from the WSJT-X UI.

Reads  captured phase  compensation  curve  estimate files  containing
fitted  polynomial coefficients  and measured  phase data  from MSK144
receptions. Intent  is to select a  compensation curve that is  from a
known transmitter like  an SDR which have good  phase linearity. Phase
plots and compensation polynomials may be viewed and compared with the
current compensation polynomial. A  suitable polynomial can be applied
to be use in all further decoding of MSK144 signals.

Plots of  the currently  selected polynomial  and its  modified higher
order terms  polynomial which is  actually used in  equalization (this
plot may  be dropped - it  is just for  kicks at the moment).   When a
captured phase analysis file is loaded plots of the measured phase and
the proposed best fit polynomial are shown.

Basic  maintenance  is also  included  allowing  clearing and  loading
captured  plots and  an option  to revert  to a  flat no  equalization
curve.

More to come on this as  amplitude equalization is also possible, this
will probably  be similar, maybe even  plotted on the same  graph with
dual  axes  for phase  and  amplitude.   Amplitude correction  from  a
measured  reference   spectrum  could  be  viewed   and  selected  for
equalization for all modes. TBC...

This   change    also   introduces    the   QCustomPlot    3rd   party
widget. Currently this  is statically linked from a  qcp library built
by the WSJT-X CMake script. This will probably be migrated to a shared
object (DLL) build as a CMake external project, once some CMake script
re-factoring  has been  completed,  which  is more  in  line with  the
QCustomPlot author's  intentions. This  will allow efficient  reuse in
other tools shipped with WSJT-X.
