Add signal_watchdog module to prevent fake demod in early phase:

1. If strong DC or low frequency sing wave like signal (suspect it is generated by ad9361 during some self-calibration like operation), put the receiver into reset
2. If the signal/header is valid, but the packet length is abnormal (signal_len<14 || signal_len>max_signal_len_th), reset the receiver
