   This method tries to update an entry with a new value. In case the entry
   did not yet exist, it will instead add a new entry. It returns whether the
   entry was added or update. If there are duplicate keys, only the first
   found element will get an updated value. Use
   <strong><code><a href="class.quickhashinthash.php#quickhashinthash.constants.check-for-dupes">QuickHashIntHash::CHECK_FOR_DUPES</a></code></strong> during hash creation to prevent duplicate
   keys from being part of the hash.
