DATABASE_MATCH via MIM curation (#213)

Bare anion label 'Fumarate' grounded to the fully-deprotonated fumarate(2-), the species present at growth-medium pH. MIM grounds bare anion labels to the bare-name CHEBI class where one exists (succinate, acetate, lactate); this acid has none, so the fully-deprotonated conjugate base is the correct target. Naive first-match enumeration would have picked the mono-anion (#213).
