7ff366abe3 Code cleanup and improvement in the JT4 decoder. 
NB: should remove the present downsampling to 11025/2 Hz, which unnecessarily
limits the availabler range of Fx Freq ("nfqso" in the source code).

b7543dce08 When SNR>90 dB is specified, simulated signal is noiseless. If Doppler spread is nonzero, then signal will have random peak amplitude. In this case normalize the signal so that peak amplitude=32767.
