SubGhz: add protocol MegaCode (#1204)
* SubGhz: add protocol MegaCode * SubGhz: check for guard time injection at the end of buffer * SubGhz: rollback samples counting in trasmitter * SubGhz: fix subghz_file_encoder_worker incorrect pulse sequence * Input: tune debounce interval * SubGhz: fix spelling in subghz_file_encoder_worker_add_level_duration Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
