[FL-1912, FL-1939] Sub-GHz frequency analyzer and add new protocol (#746)

* ToolBox: add manchester-decoder and manchester-encoder
* SubGhz: add new FM config cc1101
* Subghz: add protocol Kia
* SubGhz: fix receiving the last packet Nero Radio
* SubGhz: app protocol CAME Twin (TW2EE/TW4EE)
* SubGhz: add protocol CAME Atomo (AT03EV/ AT04EV)
* F7: sync with F6
* SubGhz: add frequency analyzer
* SubGhz: remove space from file name 
* SubGhz: frequency analyzer add filter and fix view
* [FL-1939] GubGhz: Frequency analyzer redesign
* SubGhz: fix incorrect subghz api call sequence in frequency analyzer worker
