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.
