      --------
      >>> parse_column_filters('snr > 10', 'frequency < 1000')
      [('snr', <function operator.gt>, 10.), ('frequency', <function operator.lt>, 1000.)]
      >>> parse_column_filters('snr > 10 && frequency < 1000')
      [('snr', <function operator.gt>, 10.), ('frequency', <function operator.lt>, 1000.)]
