FT8: Use GFSK waveform with BT=4.0 as reference for subtraction, for now. May want to change to BT=2.0 before v2.1 release?

For now, change to BT=1.5 for FT8. This commit enables the waterfall analysis window. This decreases sidelobes significantly in exchange for increased noise bandwidth. Sensitivity to weak tones will be degraded somewhat.
