   * @param [spectra] Input spectra (sorted by m/z)
   * @param [min_charge] The minimum charge considered
   * @param [max_charge] The maximum charge considered
   * @param [fragment_tolerance] The tolerance used to match isotopic peaks
   * @oaram [fragment_unit_ppm] Whether ppm or m/z is used as tolerance
   * @param [keep_only_deisotoped] Only monoisotopic peaks of fragments with isotopic pattern are retained
   * @param [min_isopeaks] The minimum number of isotopic peaks (at least 2) required for an isotopic cluster
   * @param [max_isopeaks] The maximum number of isotopic peaks (at least 2) considered for an isotopic cluster
   * @param [make_single_charged] Convert deisotoped monoisotopic peak to single charge
   * @param [annotate_charge] Annotate the charge to the peaks in the IntegerDataArray: "charge" (0 for unknown charge)
   *       Note: If make_single_charged is selected, the original charge (>=1) gets annotated.
