[FL-1758] SubGhz refactoring part 1 (#689) 
* SubGhz: refactoring
* WeGet: Add support for outputting formatted lines, events center button pressed, center button released
* Variable Item: slightly changed the display of data on the screen
* SubGhz: add show errors, add show preset, refactoring
* SubGhz: refactoring transmitter
* SubGhz: removed unused modules
* SubGhz: Add FuriHalSubGhzPresetOok270Async setting menu
* SubGhz: fix annotation
* SubGhz: add support Nero Radio
