SubGhz: add protocol BinRAW (binarization of data quantized by the minimum correlated duration) (#2322)
* 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
