 * Look for corresponding timing in resource timing buffer

 * - Timing (start, end) are nested inside the request (start, end)
 * - Browsers generate a timing entry for OPTIONS request
 *
 * Strategy:
 * - if a single timing match, return the timing
 * - if two following timings match (OPTIONS request), return the timing for the actual request
 * - otherwise we can't decide, return undefined
