* SubGhz: add protocol DataRAW (binarization of data quantized by the minimum correlated duration) * SubGhz: fix name history * SubGhz: add encoder Data_RAW protocol * SubGhz: decreasing the size of the LevelDuration structure * SubGhz: history, added check that there is free RAM * SubGhz: checking for free memory, support to pass without gap * SubGhz: add running average to average the result, auto cut noise at the end of a burst * SubGhz: support for repeating sequences * SubGhz: fix secplus_v2 decoder * SubGhz: bin_RAW fix add history * SubGhz: add debug * SubGhz: debug refactoring * FURI_LOG: add FURI_LOG_RAW_x formatted string output like printf * SubGhz: fix new FURI_LOG metod * FURI_LOG: fix unit test * SubGhz: add enable/disable BinRAW protocol decoding * SubGhz: fix PVS * SubGhz: forcibly turn off the speaker when exiting SubGhz * SubGhz: adaptive adjustment to the noise level Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
