/**
 * Like RxJS `timeout`, but only for emissions that are not ignored.
 *
 * Values that match `config.ignore` are forwarded immediately and do not affect
 * timeout state (`first`/`each`). Timeout timing only observes non-ignored values.
 *
 * Example usage:
 *
 *   source$.pipe(
 *     timeoutWithIgnore({
 *       first: 1500,
 *       each: 1000,
 *       with: () => of(null),
 *       ignore: value => value === undefined,
 *     })
 *   )
 *
 * @param config RxJS timeout config with an additional `ignore` matcher
 * (`(value) => boolean` or array of values) used to bypass timeout checks.
