Describe the bug

When using the library to fulfill advanced orders containing extraData for a zone contract, the fulfillOrder function incorrectly calls fulfillBasicOrder instead of fulfillStandardOrder. As a result, the extraData is not passed to the zone contract.

To address this issue, the logic should ensure that if extraData is provided, fulfillStandardOrder is used.

Relevant code sections:

• seaport.ts:879
• utils/fulfill.ts:446: The useAdvanced function should return true when extraData is passed.
