Support for WooCommerce High-Performance Order Storage

WooCommerce has introduced a new storage model for orders called High-Performance Order Storage. It will reduce order creation from at least 50 queries to just 3. Unfortunately, it seems that Stream is not compatible with HPOS: some of the currently-implemented WooCommerce support will stop working (specially, some features involving the monitorization of changes on orders)

There is a guide on how to upgrade to HPOS: https://github.com/woocommerce/woocommerce/wiki/High-Performance-Order-Storage-Upgrade-Recipe-Book

Thanks a lot for your kind support
