/**
 * Build the `vm` → display-text map for a workbook's rich values.
 *
 * All three parts are optional and any of them being absent, malformed or of a
 * structure this understands nothing about simply yields no entry for that
 * index — the caller then keeps whatever the cell's `<v>` said.
 *
 * @param metadata   `xl/metadata.xml`, or undefined when the package has none.
 * @param structures `xl/richData/rdrichvaluestructure.xml`.
 * @param values     `xl/richData/rdrichvalue.xml`.
 * @returns A map from a cell's 1-based `vm` index to the text to render.
