A small table of legacy adduct definitions retained for compatibility with
earlier SpaMTP workflows. New annotation code should use AdductRules(),
which includes charge, stoichiometry, ion-mode, and chemical-validity fields.

- adduct_name
Adduct notation.
- ion.mass
Legacy ion-mass expression.
- charge
Ion charge.
- mult
Analyte stoichiometric multiplier.
- add_mass
Exact mass shift.
- pol
