Add control of decoding "depth".

Improve the way pctile gets an estimate of array median. Put info for mettab() into a data statement. Attempt decoding near all freqs that give sync >= 1.0 Remove killbyname git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@2707 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
