[WIP] Creates a new AFSK-1200 correlation decoder and updates the

Fleetsync II decoder to use it.  Adds instrumented version of the decoder
and a new Fleetsync2 FX pane to the DemodulatorViewerFX tool.

Note: the remaining AFSK-1200 based decoders will all be ported to use
this new AFSK1200 decoder (MDC1200, Tait1200, LowJack1200).
