Wefax warning fix modulation fix (#2543)

Browse source 
* changed order of modulations, changed case to avoid capture
* added missing AMAudioFMApt mode to dump pmem
* reorder demod, adding missing ones, fix warnings
* removed uneeded 'previous_modulation', renamed WFAX to AMFM to match other places
* removing uneeded 'previous_modulation' uneeded check in change_modulation
* move capture at the end so AMAUdioFMApt is matching the other arrays for position 4
* added AMFM to Recon Level and Scanner

* clang + more details in some comments
