Include background image as it is the case in the react package

[AmaelN]

Hi,

Could you implement this feature on the NG package in order to use a progressive image in a background image css.

This functionality is present on the react project : scaleflex/react-cloudimage-responsive#4

Thanks in advance for your reply

hey @AmaelN,

it's on our roadmap, but we don't have clear ETA for it (busy with other products now)
