Update allsim.f90 and addit.f90 for the new FT8 and FT4 waveforms.

Improve FT8 SNR estimates in two ways:
...
(i) SNR no longer saturates at +20 dB
(ii) a large signal in the passband no longer causes the
SNR of weaker signals to be biased low.

Rename ft8sim files as follows:
...
ft8sim_gfsk.f90 => ft8sim.f90
ft8sim.f90 => ft8sim_fsk.f90
This change reflects the fact that the GFSK waveform is now used in WSJT-X
for ft8 and ft4.

Simplify ft4sim by removing waveform generation code and replacing it with a call to gen_ft4wave.f90.
