Threshold filtering on the FFT results

• Reads filter config from yaml
• Stores each rlrmrnt of the FftBuf in the individual ThresholdFilter

Config example

fn VaFft:
    enable: const bool true         # optional, default true
    send-to: /AppTest/MultiQueue.in-queue
    conf point Fft:                 # Conf for Point's to be exported full name will be: /App/Task/Fft.freq
        type: 'Real'                # Double / Real / Int
    input: point string /AppTest/Exit
    freq: 300000                    # Sampling freq
    len: 30000                      # Length of the FFT sequence processing at a time, also defining number of frequencies returned from the FFT
    window: 512
    filter:                 # Filter conf, for each frequency to be filtered on fly
        threshold: 0.5      #   absolute threshold delta
        factor: 1.5         #   multiplier for absolute threshold delta - in this case the delta will be accumulated
