* SubGhz: the functions of saving loading KeeLog have been modified, saving KeeLog is prohibited * SubGhz: Fix displaying Nice FlorS in the Raed scene * SubGhz: Fix displaying Faac SLH in the Raed scene * SubGhz: Fix displaying iDo in the Raed scene * SubGhz: Fix displaying Star Line in the Raed scene * SubGhz: Fix displaying Nice Flo in the Raed scene, added save and load functions. (testing needed, no remote control) * SubGhz: subghz_beginadded common encoder upload signal * SubGhz: add Came encoder * SubGhz: modified pricenton encoder, fix view transmitter hide the "Send" button if there is no encoder * SubGhz: add nice flo encoder, need testing no remote control * SubGhz: add gate_tx encoder * SubGhz: add nero_sketch encoder * SubGhz: add keelog encoder * SubGhz: add long upload upload while the button is pressed while releasing the transfer is over, with a check for sticking (maximum 200 upload repetitions) * SubGhz: fix max upload * SubGhz: Fix structure subghz add encoder * SubGhz: add generating and sending a dynamic keelog key, refactoring the code * SubGhz: add notifications * SubGhz: add creating a new remote control (Pricenton, Nice Flo 12bit, Nice Flo 24bit, CAME 12bit, CAME 24bit, Gate TX, DoorHan) * SubGhz: Fix load file, fix scene start * Subghz: Fix show key * SubGhz: Fix subghz_cli * SubGhz: Fix furi-hal-subghz * Format sources * SubGhz: standard notification scheme, fix broken assert in DMA. * SubGhz: move level alignment logic to furi-hal-subghz, fix spelling, cleanup.
