docs: Compare time, when log entries were created.
  
  It uses `meta.time` and `meta.id` to detect entries order.
  
  @param {Meta} firstMeta Some action’s metadata.
  @param {Meta} secondMeta Other action’s metadata.
  
  @return {boolean} Is first action is older than second.
  
  @example
  import { isFirstOlder } from 'logux-core'
  if (isFirstOlder(lastBeep, meta) {
  beep(action)
  lastBeep = meta
  }
