The readers that contribute to each shipped FMATCH product, keyed by OperationalMode. A reader contributes to a product when any of its product variables names that product in its VariableSpec.modes. readers/__init__.py fills this once, from the built-in readers, after they have all registered; it is empty while that package is importing.
