* ApiHal: set frequency and path in one go. Drivers: proper frequency registers calculation for CC1101. Update subghz cli to match new api. * SubGhz: preparation for parsers porting, tim2 sharing * ApiHal: add interrupts API, move all TIM2 related things there. * SubGhz: refactor protocol lib and add keeloq. * SubGhz: proper init_set for keeloq manafacture key * SubGhz: port more protocols to lib * SubGhz: load keeloq manufacture keys from sd card (if any). * SubGhz: format output from protocols. * SubGhz: use default frequency in subghz_rx cli command. * SubGhz: keeloq key types * Fix compillation error when internal storage disabled * SubGhz: minor cleanup * SubGhz: properly handle timeout and reset signal in subghz_rx * SubGhz: Worker, Capture View. Furi: emulate thread join. * SubGhz: free strings on keeloq key load end * SubGhz: update protocols reporting API, app refactoring and capture view, update API HAL usage. * SubGhz: update dump formatting * ApiHal: backport subghz preset to F5 * ApiHal: backport subghz frequency range to F5
