DATABASE_MATCH via MIM curation (#114)

Sulfur-free DL minerals is a named, recurring multi-component preparation (6 media). Searched CHEBI, NCIT, MeSH, FOODON and ENVO by label and synonym with normalisation: no term denotes it, and none could -- it is a lab preparation rather than a substance. Takes the STOCK_SOLUTION convention used by the existing mapped records: a kgmicrobe.ingredient: mint, with no parent because a multi-component mix does not narrow to any single compound (#114).
