/* Each config has a few properties:
 * - library version
 * - hw name
 *
 * We need to be able to enumerate the list of possiblities for hw
 * names given a version, and vice-versa. Ideally the list of hw names
 * across versions will be the same, but it doesn't have to match up
 * exactly.
 *
 * Unfortunately JavaScript doesn't allow arbitrary keys on maps, only
 * strings. Since we'll almost never need to access along both
 * dimensions at once, we'll just have 2 separate maps, indexing by
 * each dimension, to an array of values. Each config must also know
 * what it is so that it can be properly filtered.
 *
 * The type of context (compat/core/es) is considered to be part of
 * the library version.
