Amazon S3 Storage for WooCommerce

It would be great to have built-in support for Backblaze B2 storage (compatible with S3). Below is the simple suggested patch that enables B2 storage files simply using “b2” as a region specifier.

Patch to amazon-s3-api.php, line 127:

switch ( $region ) {
case ‘b2’:
return ‘s3.us-west-000.backblazeb2.com’;
break;
