calculate the mass accuracy of measured m/z. lazy input allowed

Common mass spectrometry tools described in John Roboz (2013) <doi:10.1201/b15436>. It allows checking element
isotopes, calculating (isotope labelled) exact monoisitopic mass, m/z values and mass accuracy, and inspecting possible contaminant mass peaks,
examining possible adducts in electrospray ionization (ESI) and matrix-assisted laser desorption ionization (MALDI)
ion sources.
