We have improved the performance speeds of VIP File System `PUT` and `DELETE` requests.
Uploads are now up to 5X faster and delete operations are up to 4X faster.

In addition, new global helper functions were added to [`a8c-files.php` in VIP MU plugins](https://github.com/Automattic/vip-go-mu-plugins/blob/a592835d08915830151e32b7e1369750ad9789a2/a8c-files.php):`
wpvip_fs_local_file_add`, `wpvip_fs_local_file_remove`, and `wpvip_fs_local_file_list`.
These helper functions can be used by WordPress applications to mark files to be
handled by the [PHP stream wrapper](https://docs.wpvip.com/vip-file-system/media-uploads/#PHP-Stream-Wrapper)
in the local temporary directory rather than being uploaded to the VIP File System.
