CW decoder

[Emmanuel SV1BTL]

CW decoder has been added to the version 1.7.0 and CW bandwidth filters have been fixed. Now CW mode is in DSB. It uses the same window for text as FT8 window does.
CW decoder is as much accurate as could it to be (not perfect). It measures audio frequency and WPM.
Try to tune near to 650-750 Hz audio for better results. If there are too many mistakes during decoding, try to refresh it by clicking CW button again, so decoder to restart. Easy to understand that when two or more CW signals being together, it would be hard to decode!...

Only these files is needed to be replaced and recompile frontend, without to restart server:
