REST API filter, Progressive image parameter
1. Cloudinary URLs in REST API calls
Cloudinary URLs now do not appear in REST API calls by default. It can be turned on by using a filter:
add_filter( 'cloudinary_allow_rest_api_call', '__return_true' );
2. Progressive image transform parameter
Added a new progressive image parameter as suggested in #20
It accepts one of four values:
'progressive' => true, // fl_progressive
'progressive' => 'semi', // fl_progressive:semi
'progressive' => 'steep', // fl_progressive:steep
'progressive' => 'none', // fl_progressive:none
