SDK version 1.17.0 release: image CTAs and active user count

Every brand has its own look and feel and every app has its own design elements. This includes custom icons, buttons and other branded assets. That's why with this SDK release you can now add your own branded assets to your stories and turn them into CTAs by giving them URLs.

Also, with this release we've added the active user count on story group level. This enables you to view how many unique users have seen the story group on their screens. You can view this metric under the performance tab in the analytics section.
