* SubGhz: fix GO0 low on last hop transmission,  decreased DutyCycle in tests
* SubGhz: test_static fix max 5 sec in transmission mode, DutyCycle <23%
* [FL-1815] SubGhz: prohibiting transmission if it is not within the permitted range for the given region
* SubGhz: fix F7 furi-hal-subghz
* SubGhz: fix logic working tests
* SubGhz: fix princeton encoder for test
* SubGhz: add log princeton encoder
* [FL-1856] Subghz: fix output a double error if the file cannot be opened
* [FL-1851] SubGhz: add deleting Stored Signals in SubGHz App
* SubGhz: add rename file SubGhz app
* SubGhz: update stats message in princeton
* SubGhz: correct spelling
* SubGhz: fix FM config,  add hardware signal processing less than 16 μs,  add added filter for processing short signals
* SubGhz: add Scher-Khan MAGICAR Dinamic protocol
* SubGhz: sync fury targets
