[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 Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
