	Function for each worker to process a list of spectra. Each peptide's
	sequence is extracted from the mgf file. Then models are chosen based on
	model. PTMmap, Ntermmap and Ctermmap determine the modifications
	applied to each peptide sequence and the spectrum is predicted. Then either
	the feature vectors are returned, or a DataFrame with the predicted and
	empirical intensities.
