/**
 * Adds support for the `format` values provided by
 * [`ajv-formats`](https://ajv.js.org/packages/ajv-formats.html).
 *
 * `format`s that apply to strings are only compared for equality, so that only
 * schemas like
 *
 * ```json
 * {
 *   "allOf": [
 *     { "format": "email" },
 *     { "not": { "format": "email" } }
 *   ]
 * }
 * ```
 *
 * include a [contradiction](https://github.com/jobohner/json-schema-describes-subset/blob/v0.4.0/docs/README.md#contradictions).
 *
 * `format`s that apply to numbers are transformed to equivalent
 * {@link AtomicSchemaObject}s like {@link MultipleOfAtomicSchema},
 * {@link MinimumAtomicSchema} or {@link MaximumAtomicSchema}.
 *
 * @example ```ts
 * import { schemaDescribesSubset } from 'json-schema-describes-subset'
 * import { formatPlugin } from 'json-schema-describes-subset/custom-plugins/format-plugin'
 *
 * console.log(
 *   schemaDescribesSubset(
 *     { format: 'email' },
 *     { format: 'date-time' },
 *     { plugins: [formatPlugin] },
 *   ),
 * ) // logs: `null`
 *
 * console.log(
 *   schemaDescribesSubset(
 *     { type: 'integer', minimum: 0, maximum: 10 },
 *     { format: 'int32' },
 *     { plugins: [formatPlugin] },
 *   ),
 * ) // logs: `true`
 * ```
 *
 * @privateRemarks TODO: return type of {@link toDNF}
 *
